Stop saying that Cee Lo Green stole this peacock-like costume from Lady Gaga. The outfit was an homage to Elton John.Cee Lo Green performed his smash hit "Forget You" at the Grammys with Gwyneth Paltrow, and the performance was insanely entertaining. The beautiful actress was onstage for an obvious reason. She covered the song in an episode of Glee last year. Seth Rogen is right. Eminem is indeed the most dangerously talented hip hop artist in history. On the music's biggest night, rapper Eminem burned the stage with his lyrical rage just as usual. R&B singer Rihanna first opened this performance with Maroon 5's Adam Levine on the piano, singing "Love the Way You Lie (Part 2)" with Eminem. Skylar Grey, the "Love the Way You Lie" songwriter, then fueled the stage and sang the haunting chorus of "I Need A Doctor", the comeback single of Dr. Dre. Eminem pinned the first two verses without a hitch and introduced Dr. Dre, who made his first live TV appearance in more than a decade.
