While we were covering The 2008 Warped Tour at Susquehanna Bank Center in Camden, NJ. We caught a performance by Katy Perry. Perry (whose single, "I Kissed A Girl," is number one on the charts right now) took to the stage around 6PM. Her stage presence and set is totally adorable. She certainly has a unique look to her with her retro clothes. Guess who else we spotted there? The frontman of Gym Class Heroes, Travis McCoy, was spotted on the side of her stage watching her perform. It looks like she could be singing to him in this picture! The two have been publicly dating since December 2007. They're so cute!
