Sandra Bullock has pulled out of the London premiere of The Blind Side, set for next Tuesday, has confirmed. The film will still be screened.

In a statement from Warner Brothers UK, Bullock, 45, tells Us

"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."

The cancellation comes as a new tabloid report claims that her husband Jesse James has cheated on her with a model.

Bullock or James, 40, have yet to comment on the specific cheating allegation, but James has interestingly canceled his Twitter account. He usually Tweets on a daily basis.

James got teary-eyed earlier this month when Bullock won her Best Actress Oscar.

"I'm so proud of her," he told at the show. "She deserves it more than anybody."

When Bullock accepted her Screen Actors Guild Award in January, she praised her normally shy husband of nearly five years for enduring the 2010 awards-show circuit.

"You get dressed up in monkey suits and you sit at a table with people you don't know," she gushed to James. She added, "I love you so much, and you're really hot. And I want you so much!"
