Eminem took the stage at the 92nd Academy Awards and surprised everyone when he started rapping Lose Yourself, 17 years after he won his own Academy Award for the "8 Mile" track — and the audience was stunned.
Martin Scorsese looked unimpressed, Idina Menzel was confused and Brie Larson was having the best time.
Marshall Mathers took to Twitter to thank the Academy for letting him do his thing — since couldn't make it to the 2003 ceremony where he received his award. He has since explained why he didn't go — in part because he thought he wouldn't win.
"Look, if you had another shot, another opportunity... Thanks for having me @TheAcademy," he tweeted. "Sorry it took me 18 years to get here."
His performance received a standing ovation.
Clowns on Twitter are posting reaction pictures of people apparently being "confused" about Eminem performing at the #Oscars. That's not what happened though. They was loving it. Only legends get this level of respect: Watch below! #eminempic.twitter.com/YHnmFa1JdO
