This week was the iHeart Musical, and while plenty of fans came out to see their favorite acts perform, there were tons of stars who came out as well.

Katy Perry and Robin Thicke set off the festival with a bang, as they got the crowd on their feet, along with J. Cole who brought out Miguel to set things off.

Unfortunately for Robin Thicke, he suffered a wardrobe malfunction during his set where a button on his shirt came undone and the zipper of his pants wasn’t cooperating!

Other celebrities came out to show support and to bust a move in the crowd, including Christina MilianMary J. BligeKat Graham, and Ne-Yo.

This weekend, Justin Timberlake and Drake and Maroon 5 are set to shut down the rest of the festival with some great performances!
