Sandra Bullock Backs Out of Another Premiere

The Berlin, Germany premiere of The Blind Side has been scrapped, a Warner Bros. rep confirms to UsMagazine.com. The reason? Its Oscar-winning star, Sandra Bullock, has cancelled her planned appearance.

It's the second time in less than a week that Bullock, 45, has bailed on an international red carpet event for her hit film.

Last Wednesday, she pulled out of this week's Blind Side screening in London amid tabloid reports of husband Jesse James' 11-month affair with tattooed model Michelle "Bombshell" McGee. (The screening is still reportedly taking place without her.)

Update: James — married to Bullock for nearly five years — recently released the following statement to UsMagazine.com:

"The vast majority of the allegations reported are untrue and unfounded.  Beyond that, I will not dignify these private matters with any further public comment.  There is only one person to blame for this whole situation, and that is me. It's because of my poor judgment that I deserve everything bad that is coming my way.  This has caused my wife and kids pain and embarrassment beyond comprehension and I am extremely saddened to have brought this on them. I am truly very sorry for the grief I have caused them.  I hope one day they can find it in their hearts to forgive me."

Last week, Bullock reportedly moved out of the Huntington Beach, Calif. she and her husband shared.

Since the scandal broke, James, 40, has stepped out in public — dropping his children off at school, returning to work at West Coast Choppers — wearing his wedding ring.

Bullock remains in hiding.
