WATCH: Taylor Swift and Jennifer Lopez Perform “Jenny From the Block”
“You know how you have your favorite song that you just play over and over again in your room?” Swift asked the crowd.
She continued, “And you sing it in front of your mirror into a hairbrush? And you have that favorite song to dance to? Los Angeles, this is my hairbrush song.”
With that, Lopez emerged on stage, and the pair performed her 2002 hit, “Jenny From the Block.”
