Well then. That was quite the surprise.
Look who unexpectedly showed up to the Oscars on Sunday?! THE "Slim Shady" himself -- Eminem.
It appeared that the audience was unaware of the surprise, too.
The rapper, whose real name is Marshall Mathers, performed his 2002 hit, Lose Yourself, which was featured in the film, 8 Mile, and earned him an Oscar for "Best Original Song" at the 75th Academy Awards.
In a tweet, the rapper said: "Look, if you had another shot, another opportunity... Thanks for having me @TheAcademy. Sorry it took me 18 years to get here."
He took to the stage shortly before the awards for sound editing and mixing were announced.
