“Rachel vs. Kate: It’s war!” blares a headline from In Touch, which goes on to claim that Kate Beckinsale hates her ex Michael Sheen‘s new girlfriend, Rachel McAdams.

Although Sheen and Beckinsale haven’t been together for eight years, and get along great co-parenting their 12-year-old daughter Lily, the mag says “she’s got her claws out when it comes to Michael’s new love, Rachel.”

According to a so-called “insider” for the tabloid, “Rachel and Kate make a point to avoid each other, and it seems like it’s Kate who’s the resistant one.”

The source notes that Sheen recently dropped Lily off at Beckinsale’s hotel, and McAdams was “steaming” because “she couldn’t even go upstairs or inside with him.”

“There are opportunities where Michael could bring Rachel along, but he doesn’t,” adds the supposed “insider.”

Well, that would be incredibly awkward… if it weren’t totally bogus.

But a rep for Beckinsale confirms to Gossip Cop, “There is no truth to it at all.”

Once again, In Touch remains hopelessly out of touch.

After UsMagazine.com titled a post “Rachel McAdams Flashes Engagement Ring?” – complete with a photo of Morning Glory star wearing a ring – a slew of outlets quickly regurgitated the speculation that she’s engaged to boyfriend Michael Sheen.

Zimbio, for instance, wrote that McAdams “was seen out and about in LA wearing what looked like a diamond engagement ring on her left hand. So either she wants us to think she’s getting hitched, or she actually is heading down the aisle with Sheen.”

Or maybe…

It’s just a plain, old ring.

“This isn’t true – they are not engaged,” a rep for Sheen assures Gossip Cop.

UPDATE 9:55PM:

Gossip Cop has just confirmed that Michael Sheen, who plays Aro in “New Moon,” is scheduled to appear on “The Late Late Show with Craig Ferguson” on November 23.

More updates from Ferguson’s program and others to come…

3:23PM:

As you probably know, the Twilight Trio of Robert Pattinson, Kristen Stewart, and Taylor Lautner will all be seen together on “Jimmy Kimmel Live” on November 20, the very same day that “New Moon” hits theaters nationwide. But if you were thinking of trying to get tickets to that show, forget it.

Forget it for two reasons. One, the cast will NOT be at Jimmy Kimmel‘s studio on November 20. As Gossip Cop can confirm, the three stars will tape the show exactly two weeks before on November 6. But there’s no use in trying to get tickets to that show either. Unfortunately, Gossip Cop has learned that there are no tickets remaining to that taping.
