No one will accuse Eminem of half-assing his Grammy performance this year, as he enlisted a star-studded, high-profile cast of performers to help him bring the proverbial roof down! First up was Rihanna singing “Love the Way You Lie (Part II),” backed by Maroon 5’s Adam Levine on the piano. This song naturally morphed into “Love the Way You Lie,” when Eminem picked up the mic to spit his verse of their shared Grammy winning song. This transitioned into “I Need a Doctor” when Dr. Dre emerged on stage to join up with Em and Skylar Grey for her debut performance. It was a great performance, which if you will now watch below. Oh and please forgive the audio cutting out near the end, that is just CBS’s terrible quality control. Enjoy!
