Sandra Bullock pulls out of another 'Blind Side' premiere

sandra-bullock-pulls-out-blind-side-premiere.jpgAmid all the news of husband Jesse James' alleged extramarital affair with a tatted stripper, Sandra Bullock is apparently staying out of the public eye and canceled her appearance at the Berlin premiere of her film, " The Blind Side."

"Without Sandy, it just didn't make any sense to have a premiere," a studio source tells E! News.

Sources say that since the alleged affair with Michelle "Bombshell" McGee has come to light, Sandra has been in hiding. This is the second premiere that the Oscar-winning actress has pulled out from.

Sandra cancelled her trip to London's "Blind Side" premiere last Wednesday citing 'unforeseen personal reasons." The studio source says they're not sure when she'll come out of hiding.

A week ago, Sandra moved out of her and Jesse's L.A. home after Jesse's reported mistress had come forth with shocking details of their affair. While Jesse hasn't confirmed the alleged affair, he issued a public apology days later.
