Woman of the Year #2: Katy Perry. From the moment her "California Gurls" video debuted at the MTV Movie Awards, it was clear Katy was beating the daylights out of the sophomore slump. Her second album, Teenage Dream, debuted at #1 on the Billboard albums chart and is nominated for four Grammy awards. She also added new husband Russell Brand to her trophy case in 2010.
