Kelly Clarkson performed in 8 Mile at Detroit's DTE Energy Music Theatre on Friday and covered Eminem!
Believe it or not, the pop sensation rocked a completely shocked house with an unbelievable cover of Eminem's Lose Yourself!!

According to Kelly they have a fan request portion of the show and the fans overwhelmingly requested Eminem.  I had no idea Kelly was talented enough to pull it off, but her own version of this song is incredible.
It would've taken me months just to memorize the lyrics.
