Michelle "Bombshell" McGee claims she slept with Jesse James for about eleven months, and provides intimate details, which has landed the allegations on the cover of In Touch magazine. The magazine reports: While Jesse has had an 11-month affair with Michelle "Bombshell" McGee, she believed he and Sandra were no longer together. "I would never have hooked up with him if I thought he was a married man," Michelle says. "He gave me the impression they were separated." For weeks, while Sandra was in Atlanta shooting The Blind Side, Michelle hooked up at least once a week with the Monster Garage star. She says their relationship was intimate and highly charged.

And now Sandra Bullock has canceled her appearance at the London premiere of "The Blind Side" amid Internet reports she is having trouble in her marriage and has left the couple's Southern California home.

The Associated Press has been unable to confirm the reports, and calls and e-mails to representatives for Bullock and her husband, celebrity motorcycle builder Jesse James, weren't immediately answered.

The 45-year-old actress said in a statement by Warner Bros. UK that she cannot attend next Tuesday's premiere for "unforeseen personal reasons." She canceled her appearance two weeks after winning an Oscar for her performance in the movie.

Bullock goes on to apologize for canceling her commitment and to thank people for their support of the film, which has made nearly $253 million domestically.

She and James were married in July 2005.
