Worst: Katy Perry
Perry came out hard against ex-husband Russell Brand while performing her "new" song "Part of Me" (actually a track that didn't make the cut on "Teenage Dream" but which will be released tomorrow - look for Katie Hasty's review), but the garish production was far too silly and over-the-top to elicit much in the way of genuine feeling or sympathy for the pop star. From Perry's hideous superhero-esque bodysuit that looked like a $40 Halloween costume to the pools of shooting fire and exploding glass, the calculated artificiality of it all felt bizarrely inappropriate given the circumstances. Frankly, it's hard to imagine Brand losing much sleep over this nonsense.
