In perhaps the most anticipated event of the 2011 Grammy Awards, Eminem took the stage with Rihanna, Skylar Grey and Dr. Dre for a seven-minute performance.

Eminem and Rihanna opened with Part II of their collaborative hit, “Love The Way You Lie,” with Maroon 5’s Adam Levine on the keys and as her vocals soared, Eminem appeared amid a fiery background.

Rihanna sounded so good, you'd never know she battled laryngitis and bronchitis leading up to the show, while Eminem's animated effort was brilliant as usual ... After "Love the Way You Lie," he performed another slow-building track with female backing. Skylar Grey joined in on "I Need a Doctor," as did his one-time mentor.
