Jesse James cheating on Sandra Bullock?

(FOX 25 / MyFoxBoston.com) - Actress Sandra Bullock may have been blind-sided by her husband's cheating heart.

Bullock pulled out of the London premiere of “The Blind Side,” citing personal reasons and it may be because of husband Jesse James' wandering eyes.

The 45-year-old actress says in a statement released by Warner Brothers UK that she can't attend the event for "unforeseen personal reasons." She goes on to apologize for canceling her commitment and to thank people for their support of the film.

Tattoo model Michelle "Bombshell" McGee tells In Touch magazine that she and James had a month-long affair in 2009 while Sandra was away filming the very movie Bullock just won an Oscar for.

Bullock and James have been married for almost 5 years and were awarded custody of James' 5-year-old daughter, Sunny, whom James had with his second wife, porn star Janine Lindemulder.

Curiously, James deleted his Twitter account today.
