[artist id="502642"]Eminem[/artist] delivered a knockout at the Grammy Awards.

The Detroit rapper was emphatic and forceful with his rhymes as he paired with Rihanna and Maroon 5's Adam Levine for an intense rendition of his Grammy-nominated hit "Love the Way You Lie."

Rihanna opened the performance from afar with Levine flanking her as the duo were placed in the center of the audience. The star crooned the opening lines of her rendition of the hit song from her album Loud.

"On the first page of our story, the future seemed so bright," she sang, as Levine joined in playing piano. "Then this thing turned out so evil/ I don't know why I'm still surprised/ Even angels have their wicked schemes/ And you take that to new extremes/ But you'll always be my hero/ Even though you've lost your mind."

Eminem then appeared on the stage behind them in a trim leather jacket and matching black shirt and jeans. With flames burning behind him on the LCD screen, he spit a rousing rendition of his powerful song.

"I can't tell you what it really is/ I can only tell you what it feels like," Em spit. "And right now there's a steel knife in my windpipe/ I can't breathe but I still fight while I can fight/ As long as the wrong feels right."

Rihanna, in a dress rivaling Cee Lo's outfit in extravagance, joined Eminem onstage midway through his rap, after a slow amble through the theater aisles. She punctuated Em's stirring vocals with the song's original refrain, bellowing the complex chorus before giving way to "Love the Way You Lie" songwriter Skylar Grey.

Grey, signed by "Love the Way You Lie" producer Alex Da Kid, launched into "I Need a Doctor," the Detox single by Dr. Dre featuring Eminem.

"I need a doctor," she sang over and over.

Eminem attacked his first two verses and then was joined by Dre onstage.

In a matching leather jacket, T-shirt and jeans (but with bright, white sneakers in contrast to Em's black ones), Dre arrived and delivered measured rhymes.

"Went through friends, some of them I put on, but they just left," Dre rapped. "They said they was riding to the death/ But where the f--- are they now, now that I need them?/ I don't see any of them, all I see is Slim."

The Grammy appearance marked Dre's first live TV performance in more than a decade.
