Did Eminem Lip Sync During His Performance On Saturday Night Live?

Eminem was the musical performer on Saturday Night Live over the weekend and Kerry Washington was the host. And there has apparently been a lot of debate online about whether he lip-synched or not.

I have seen him live several times. My opinion is he had his song running in the background as he rapped over it. I think that is how he does many of his performances. I do know one time I saw him live, he started a 50 Cent song and messed up the lyrics and started laughing and said "I totally effed that up...lets start this over!" and he did which I thought was funny and showed he makes mistakes just like all of us!

Watch the video and you be the judge. Let me know if you think he's lip synching or not.
