Katy Perry is quite the popular lady these days. A multitude of famous friends attended her Tuesday evening performance at NYC’s Hammerstein Ballroom, including pop star Rihanna. She showed up for Katy’s awesome live act, sitting in the VIP area and singing along and dancing while Katy performed!
In addition to Rihanna, Gossip Girl star Leighton Meester was spotted hanging out backstage, while mogul Donald Trump and his wife schmoozed in the VIP area. Who knew the Donald was into girls kissing girls? It appears that Rihanna’s just a regular chick that goes to concerts and gets excited for her favorite songs. Well, except for the fact that she gets to go backstage after the concert and hangout with Katy as though they’re besties! If you could hangout with one pop star behind the scenes at their show, who would it be and why? Let us know in the comments!
