Pop star Katy Perry had a huge year both personally and professionally. She represented Summer 2010 with her hits "California Gurls" and "Teenage Dream" and kept the jams coming all year with the release of "Fireworks" and "ET." The singer also debuted her first perfume, Purr. Katy married Russell Brand in October in a lavish Indian ceremony, and the newlyweds have been each other's best red-carpet accessories ever since. She shared a peak at her secret nuptials during her performance at the Grammys, where she was nominated for four awards. She's currently on tour with her Teenage Dream album.
