Motorcycle enthusiast Jesse James reportedly told Michelle 'Bombshell' McGee his marriage to the actress was over and romanced her while the actress was away filming 'The Blind Side' - the film which won her the Best Actress Oscar.

McGee said: "I would never have hooked up with him if I thought he was a married man. He gave me the impression they were separated."

Recalling their first meeting - which took place after Michelle emailed him enquiring about the possibility of modelling for his West Coast Choppers business - the brunette beauty says Jesse made it clear he was interested in more than just working with her.

Jesse, 40, took Michelle on a tour of his garage, before taking her into his office and locking the door.

She added to America's In Touch Weekly magazine: "We ended up on the couch. He wanted to watch movies, but I asked him, 'What's going on with you and Sandra?' He said, 'She doesn't live here. She has a house in Austin. She is filming, and I can't talk about it.' "

Michelle says they slept together and from that point, began texting each other several times a day and met up at least twice a week for the next five weeks.

Jesse - who married Sandra in July 2005 - recently spoke of his pride in his 45-year-old spouse after she won the Best Actress prize at the Academy awards earlier this month.

He said: "It's a once-in-a-lifetime opportunity to support my wife and her work. She does it all the time for me. She goes to Mexico, to the desert, to the hospital - a lot - to support me and my work. The least I can do is put on a suit and support her.

"She's beautiful. She's amazing. She takes my breath away. Sometimes I look at her and I do, I just lose my breath.”

Sandra was due to fly into the UK next week to promote 'The Blind Side' but it was announced yesterday that the premiere and all other promotional commitments had been cancelled.
