Demi Lovato is performing a live concert for the first time in almost a year.

The singer announced today on Ryan Seacrest‘s radio show that she’s giving two shows in September as a special “thank you” to her devoted fans.

Lovato will perform at New York’s Hammerstein Ballroom on September 17 and at Club Nokia in Los Angeles on September 24.

The teen star told Seacrest, “These shows are basically thanking my fans for being so supportive throughout this entire journey,” and noted, “This is the first time that I will be on stage in about a year.”

Lovato taped a performance of her hit new single “Skyscraper” at the Do Something Awards last week, but she hasn’t had a live show since dropping out of the Jonas Brothers‘ international tour last fall to go to rehab.

Tickets for boths show go on sale August 26 at 10 a.m.

Audio of her interview with Seacrest is below.

On the heels another major collaboration, here’s one that could be very compelling in its own right – Joe Jonas and Chris Brown are working together.

The producer Hit-Boy tweeted a photograph of himself with the two performers, along with the message, “Swag! @joejonas @HitBoy_SC @chrisbrown just did a smash!”

Neither camp has confirmed the team-up, and there are no additional details about the potential joint track.

The two popular artists have decided to collaborate at what could be a pivotal time for both.

Jonas is attempting to fashion a solo career separate from the massive success of Jonas Brothers, while Brown’s strong sales have been overshadowed by a new round of public image problems.

Are you looking forward to hearing a Jonas-Brown track?

Demi Lovato has left rehab, Gossip Cop confirms.

A source close to the star tells us she came back to Los Angeles earlier this week, having completed her prescribed treatment.

She also did some outpatient rehabilitation.

Lovato will continue to see her L.A. doctors to deal with her existing issues.

In late October, Lovato left touring with the Jonas Brothers in order “to seek medical treatment for emotional and physical issues she has dealt with for some time,” her spokesperson said at the time.

Demi Lovato will be with her family on Christmas.

The “Sonny with a Chance” star will be permitted to leave a treatment facility for the holiday to be with her loved ones, Gossip Cop can confirm.

She’ll return that evening.

Lovato has been in treatment for “emotional and physical issues” since leaving her concert tour with the Jonas Brothers nearly two months ago.

Zack Taylor was the first to report the Christmas news.

Alex Welch, the young dancer who was allegedly punched by Demi Lovato, is now speaking up.

“To this day, I haven’t gotten an apology. I’ve heard nothing,” she tells People magazine. “That’s sad if you think that person is your friend.”

A source close to Lovato tells Gossip Cop, “Demi is focused on her treatment right now and hasn’t been able to call Alex directly,” but adds, “Her mother and stepfather have reached out through intermediaries to both Alex and her parents – they were told that they did not wish to speak with them.”

Regardless, Welch says before the fisticuffs, tour managers gave Lovato a talking to because “she had gotten in trouble” the night before.

What precisely happened is not mentioned.

Welch goes on to relate that Lovato was upset about being snitched on, and “pulled the dancers in a room and threatened: ‘If I find out who told on me …’ ”

Because Welch hadn’t witnessed the incident the night before – and hadn’t spoken to anyone about it – she didn’t think twice about Lovato’s warning.

Next thing she knows, says Welch, “We were on the plane with the Jonases having this awesome time and… she walks up and punches me and literally walked away and got in her seat.”

What followed was Lovato checking into a facility for “emotional and physical issues,” while Welch was left with a black eye and bruised cheekbone.

Though Welch didn’t suffer any permanent damage, she’s considering civil litigation.

What do you think of Welch’s story?

Demi Lovato checked into treatment after fighting with a dancer.

Earlier whispers that the altercation was the catalyst for Lovato’s decision to drop out of an international Jonas Brothers tour and head to rehab appear to be accurate.

Lovato entered a professional treatment facility on Monday for “emotional and physical issues” including eating disorders, bullying and cutting.

Gossip Cop has reached out to Lovato’s rep for further information.

Demi Lovato has quit a concert tour with the Jonas Brothers and entered a treatment center to deal with “emotional and physical issues.”

The singer is reportedly not treating drug use.

“Demi Lovato left her tour early this weekend in order to seek medical treatment for emotional and physical issues she has dealt with for some time,” her spokesperson said in a statement.

“Demi has decided to take personal responsibility for her actions and seek help. She is doing just that.”

“She regrets not being able to finish her tour, but is looking forward to getting back to work in the near future.”

Her disappearance from Twitter over the weekend caused many fans to speculate about her personal life.

“EXCLUSIVE! ‘Breaking Dawn’ Drama: Joe Jonas Is Possessive Of His GF Ashley Greene…Especially When It Comes To Jackson Rathbone!” reads a headline from the overly dramatic HollywoodLife.

According to the site, which has given us carpal tunnel syndrome for having to correct it all the time, “Joe Jonas is jealous over his girlfriend Ashley Greene’s sexy physical scenes as her character Alice Cullen with her on-screen hubby, Jackson Rathbone (Jasper Hale) — and he’s making sure everyone knows she’s HIS girl.”

Uh, huh…

HollywoodLife says it has a “source” who claims, “Joe is very possessive of Ashley — letting everyone know that she belongs to him –- especially [when it comes to] Jackson.”

Uh, huh…

Here’s what’s accurate: Joe Jonas and Ashley Greene are dating. And Greene and Jackson Rathbone play husband and wife in Breaking Dawn.

Here’s what’s inaccurate: Everything else.

A source close to the Jonas Brothers assures Gossip Cop that the singer/actor knows the difference between play acting and real-life, and that he’s not remotely jealous of Rathbone. The source calls the HollywoodLife story “nonsense.”

If there’s as much drama onscreen in Breaking Dawn as HollywoodLife manufactures about the movie’s stars, it will be another box office hit.

Following in the footsteps of Kim and Khloe Kardashian, and even Adrian Grenier, Joe Jonas is changing zip codes.

The Jonas Brother will guest star as himself in a November episode of the CW series “90210.”

The premise of the storyline involves Jonas escorting Jessica Lowndes‘ Adrianna to a magazine cover party, reports EW.com.

Grenier and his band The Honey Brothers appear on tonight’s episode, and the Kardashians made their cameo last week.

Who knew Nick Jonas was a triple threat?

After tackling the music world with the Jonas Brothers and television with “JONAS,” the wannabe presidential candidate will be making his West End debut next month.

Jonas will star in the London production of “Les Miserables,” his rep confirms to Gossip Cop.

He’ll play a student named Marius, during a three-week run beginning June 21.

It’s not Jonas’ first time starring in the show.

“When I was ten years old I was in Les Miserables as Gavroche,” he tweeted. “On my closing night in 2003 I told my parents that I would come back to be Marius one day. It is truly a dream come true.”

“The Beckham’s Are Going Pop,” writes Hollyscoop, which can’t even spell “Beckhams” correctly.

According to the site, “The Jonas Brothers have invited Brooklyn, Romeo and Cruz [Beckham] to appear in their new music video after meeting them at a concert last Saturday.”

Says a so-called Hollyscoop source, “Kevin, Joe and Nick were really pleased to meet the Beckham’s (sic) and they invited the children to be part of their new video.” 

Adds the language-challenged site, “The trio will be filming the video next week in Malibu, so we’ll keep you guys updated with more info in case you wanna do some stargazing with the Beckham’s (sic).”

Typing “Beckhams” incorrectly once could be a typo.

Twice, a bad pattern.

Three times, a sign of total ineptitude.

But more importantly, the Beckhams (or Beckham’s – haha) are NOT doing a Jonas video this weekend.

A rep for the singing siblings tells Gossip Cop, “There’s no video in the works.”

And David Beckham‘s spokesman also said the story was “not true.”

Geez, Hollyscoop couldn’t get a story right if we spotted them the R, I, G, H and even T.

The Magic Kingdom’s glow has dimmed.

Disney superstars Selena Gomez and Nick Jonas have broken up again.

A busy work schedule for both young performers led the couple to split early last month, although a source tells Gossip Cop, “The two have a special bond.”

While Gomez and Jonas never publicly acknowledged their second romantic go-round, our source confirms they tried but are not together anymore.

Gomez is adding clothing design to her already packed singing and acting career, while Jonas is expected to tour with brothers Joe Jonas and Kevin Jonas this summer.

Are the Jonas Brothers going their separate ways?

“Someone call tween 911,” cries a PopEater.com report, “There is trouble with a capital ‘T’ in Jonasword.”

The story suggests an “impending” split for Kevin Jonas, Nick Jonas, and Joe Jonas “may be in store for 2010.”

According to the site’s quoted “family insider,” recently married “Kevin’s heart is just not in the group anymore,” while a “friend” claims “Nick sees himself as the next Justin Timberlake and brother Joe knows it.” As for whether a Nick solo career could co-exist with the group’s continuing joint projects, PopEater recalls “what Diana Ross told the Supremes!”

(Translation: No.)

But Jonas Brothers fans should know that PopEater’s warnings do NOT match what the brothers themselves are saying within the past twenty-four hours.

“We really believe that this is going to be the busiest and best year ever for the Jonas Brothers,” they Tweeted on New Year’s Eve. They discuss starting to shoot the second season of “Jonas” for Disney “at the beginning of February” and also say, “We are in the beginning stages of planning our next World Tour 2010.”

Anything can happen, of course, but Gossip Cop doesn’t think that sounds like “trouble with a capital ‘T.’”

On a snowy day in New York, Kevin Jonas traded in his purity ring for a wedding ring when he swapped vows today with Danielle Deleasa.

The young couple married at the Oheka Castle on Long Island, New York in front of 400 guests, including Demi Lovato.

The bride, a former hairdresser, looked radiant as she walked down the aisle in a Vera Wang gown. Brothers Joe and Nick served as best men.

Guests celebrated under a heated white tent, decorated with trees adorned with hydrangeas and sparkling crystals.

Kevin and Danielle met in 2007 while vacationing with their families in Bahamas.

The newlyweds told People magazine, “We’re so happy that we’re finally married and we were able to share the special moment with family, friends and loved ones.”

Perez Hilton‘s reporting usually gives Gossip Cop a chuckle, but sometimes his nastiness just makes us wince. Hilton, who’s never been too ashamed to go after celebrities’ children, now seems intent on making brutal remarks about underage personalities just for shock value.

Hilton’s latest bit of classy commentary, “Aliana Lohan Works the Streets of Paris,” jokes that Lindsay Lohan‘s little sister is prostituting herself for drug money. He scribbles, “How much?” on a photo of Lohan on a sidewalk, and writes, “Ali teaches Linds a lesson on how she’s going to be making her money seeing as both her fashion and acting careers are tanking.” He then draws specks of cocaine beneath Lohan’s nose.

Trust us, we understand that Lohan dressed provocatively, and that as an actress she is subject to public scrutiny. But Ali Lohan is just 15 years old. Is it really necessary for Perez Hilton to joke that she’s working the streets for drug money?

Oh, but the classy treatment of teenage celebs doesn’t end there. In another post, Hilton manages to turn on the sincerity for a brief moment, praising Joe and Nick Jonas for attending the Canadian Breast Cancer Foundation’s “Run for the Cure.” “Their mama should be very proud!” Hilton declares. Gossip Cop agrees: she should be.

But in that post about women battling a potentially fatal disease, Hilton scrawled the words, “Save the Boobies” across an accompanying photo. This is about saving lives, but “Scoop” couldn’t just leave well enough alone. He had to treat an issue as serious as breast cancer like a joke.

We like blogs that have fun. But there’s a thick line between funny and mean, and once again Perez has crossed it.

The Jonas Brothers are such enormous stars with so few personal scandals, the press sometimes needs to make headlines out of a complete non-story. So when reports came out that Kevin Jonas had asked Danielle Deleasa to sign a pre-nuptial agreement, gossip sites decided it spelled doom.

Outlets are announcing that the pre-nup “puts their wedding on hold” and that the pending marriage “could be in trouble!” Deleasa is allegedly furious with Jonas’ request, with her friends saying she thinks he “doesn’t trust her.”

Gossip Cop wonders where all of these headlines came from, especially when no one has actually seen paperwork for a pre-nup.

While a representative for Jonas declined comment, another source close to the star told Gossip Cop there was no truth to rumors that his impending nuptials are in peril. We’ll keep an eye on it, but for now it just seems like fabricated Disney drama.

There was speculation that Joe Jonas might be an “American Idol” judge, then stories that all three brothers would be judges, but Gossip Cop has confirmed with the trio’s rep that “Joe will be a guest judge on one episode” of “American Idol,” and it will be “Joe only” and not Nick or Kevin.

Joe will be joining such other guest judges as Victoria Beckham, Mary J. Blige, and Shania Twain.
