Sandra Bullock breaks her silence and responds to rumors of a sex tape with husband Jesse James

Scandals and rumours are running continuously in Sandra Bullock's life. She has finally broken her silence since news of Jesse James' alleged affairs made headlines - denying the existence of a purported sex tape with her estranged husband.

"There is no sex tape," she told People.com. "There never has been one and there never will be one."

According to a source who watched one of the videos, a naked woman is seen on her knees with her hands bound, while James is wearing a Nazi hat and waving his arm in a salute.

James, 40, checked himself into the Arizona facility on March 26 "to deal with personal issues" in the hope of saving his five-year marriage to the Oscar-winning actress, his rep said in a statement.

Though none of the alleged sex tapes are up for sale, they are reportedly not kept in a secured location.

"They could end up being made public just like the photo of Jesse giving the Nazi salute," the source said. "There's no doubt some of these tapes could leak and end up on the Internet."

According to his attorney Joe Yanny, James is hoping that rehab and some privacy will help him recover and mend his relationship with Bullock.

"This whole thing has destroyed Jesse's entire universe," Yanny told The Associated Press. "Right now, he's a broken man."

"Jesse is in love with Sandra. The single most important thing to Mr. James and the children is that the marriage somehow survive."
