Katy Perry gave an unforgettable performance of her new singe 'Part of Me' at the 2012 Grammys. The song was clearly aimed at her ex-husband Russell Brand. Adele sang in public for the first time since her throat surgery and didn't disappoint. And Jennifer Hudson's tearful rendition of 'I Will Always Love You' also left everyone's jaws on the floor.
