Magician David Copperfield once tried to force himself on a woman in the back of his limousine, his former chauffeur claims. John St. John has told the National Enquirer the incident took place in Ottawa, Canada in 1996, while Copperfield, 51, was engaged to Claudia Schiffer.

St. John was ordered to pick up the woman - a Schiffer lookalike - and then drive around the city while Copperfield attempted to seduce her.

He tells the tabloid, "I know when someone is having consensual sex in my limousine, but what was going on this time was different. They were struggling and I heard raised voices. I could hear the girl saying: 'No. Get off me' and 'Stop'. It was the first time as a driver that I didn't know what to do. I am a father of three daughters and I knew I would be kissing my career goodbye by dragging Copperfield out of the car - but I thought I had no other option. Just then I heard David call me on the intercom saying: 'Take me back.'"

Copperfield's representatives have described St.John's claims as "fiction" but they come at the same time a U.S. grand jury is investigating the star for the alleged rape of a 21-year-old woman in the Bahamas in July.

St. John has offered to testify against the illusionist in court if asked to recount his claims.
