Katy Perry's swing looked like a high school–yearbook photo backdrop, but her cupcake-esque minidress and the video of her actual wedding, to British comedian Russell Brand last October, made up for it. Perry is the pop-music equivalent of a basket of puppies. This Valentine's Day–themed performance makes me want to believe that she and Brand will stay married forever, despite the statistical improbability of that happening. Good luck, you crazy kids.
