Eminem Cracks -- Admits Involvement in Taintgate

In case you still believe the Eminem/Sacha Baron Cohen incident from the MTV Movie Awards was real... Em just proved you're a gullible Gary by admitting he was knee deep in Sacha's butt stunt.

Em became the 496th person to confirm the whole thing was planned, telling RapRadar.com, "Sacha called me when we were in Europe and he had an idea to do something outrageous at the Movie Awards. I'm a big fan of his work so I agreed to get involved with the gag."
