There's a lot of debate online whether or not Eminem lip-synched when he performed on "Saturday Night Live" this past weekend. Eminem hasn't commented and although there wasn't any one moment that "proved" that he wasn’t singing he did seem offbeat at times. There could also be some glitches in the sound and picture, even if it's a "live" broadcast. On top of that, Eminem's first performance, "Berserk", includes multiple layers of vocals, so it's hard to decipher what's him, what's sampled and what's part of a backing track.

Regardless, Eminem's career was started by his dominance in live rap battles, which included improvisation and intricate, complicated freestyles. In the end the “8 Mile” star would seem like one of the least-likely rappers to lip-synch. Check out his performances below
