SNL Claims Another Singer

According to this story, this week it was Eminem who lipsynced:

Bosses of American satirical show Saturday Night Live were left embarrassed by Eminem last night when the rapper lipsynced through parts of his two performances on the show. A week after Ashlee Simpson's miming fiasco made headlines, Eminem failed to keep up with his own guide track as he performed politically-charged "Mosh" and new hit "Just Lose It."

Think he'll blame it on acid reflux? Or maybe he'll call it a prank. Y'know, say he was making fun of Ashlee Simpson from last week. Perhaps this is a new trend in SNL music performances?
