A tattoo model has alleged that she had an affair with actress Sandra bullock's husband, while she was busy filming 'The Blind Side' that won her an Oscar for Best Actress.

Michelle 'Bombshell' McGee has claimed that she had a month-long affair with Jesse James, while Bullock was in Atlanta for the shoot in 2009.

"I would never have hooked up with him if I thought he was a married man," Fox News quoted her as telling In Touch.

She revealed that she had sex at least once a week with the 'Monster Garage' star.

McGee further claimed she had first contacted James for a modeling contract at his company West Coast Choppers.

Apparently, James requested her to send photos to his personal email.

And then she met him at his office, where she even asked him about Bullock.

She said: "He said, 'She doesn't live here. She has a house in Austin. She is filming, and I can't talk about it."

Meanwhile, Bullock has cancelled her appearance at London's premiere of 'The Blind Side' after McGee's revelation.

She said in a statement: "Due to unforeseen personal reasons a trip abroad to support 'The Blind Side' has been deemed impossible at this time.

"I apologize for any inconvenience this may have caused and thank you for your continued support of the film."

James was married to porn star Janine Lindemulder in the past. (ANI)
