Katy Is Hot!

Katy Perry was filming her new music video "Hot N Cold" in Los Angeles yesterday, and we got an exclusive behind-the-scenes sneak peak! The "I Kissed A Girl" hottie wore a pink wedding dress for half of the shoot, and then ripped it off to reveal a seriously sexy one piece for the rest of the scenes. And yes, in the wedding scene, her maid of honor is a dude in drag - loves it!

Katy chatted with our photogs, and fans on the set gave a shout out to the singer, thanking her for letting them appear in her vid. She's our kind of rock star!
