Katy Perry picked a green strapless Giambattista Valli dress for today's White House Correspondents' dinner in Washington, DC. She was among the many ladies who hit the red carpet at the Washington Hilton for the dinner, which is being emceed by Conan O'Brien. The fun kicked off early for celebrities at Correspondents' Dinner pre-parties. Katy, though, skipped those events and held out for the dinner, which also brought out the President and First Lady. Katy's connection with the Obamas is deep — she was a big campaigner for them in 2012 and attended the Inaguration earlier this year.
