She’s always up for a good shindig, and last night (April 18) Katy Perry was in the house for the 2012 ASCAP Pop Music Awards.

The “I Kissed a Girl” songstress showed up at the Renaissance Hotel in Hollywood, sporting a beautiful art deco-style gown as she posed for the press.

And it was a big night for Katy, who nabbed a trophy for her hit song “E.T.” as did her producing trio of Max Martin, Ammo, and Dr. Luke.

Speaking of Max Martin, the Swedish hitmaker took home the coveted title of Songwriter of the Year.
