Eminem: I didn't mime

Eminem has hit back at claims he mimed on American TV show Saturday Night Live, insisting he sang over a vocal track.

Newspaper reports claimed the rapper lip-synched to his new single Mosh just a week after pop star Ashlee Simpson was caught miming on the very same show.

A studio source said: "He was singing 'Mosh' and you could tell he was lip-synching. The track was just a bit ahead of his lips and he put the mike down at one point but the track kept going."

But a representative for Eminem insists he was trying to "duplicate the sound on his album," telling PageSix.com: "He had a vocal track on for double vocal effect on the first song, to make it more powerful. Lots of hip-hop artists do that. Tupac Shakur did it."
