LOS ANGELES (AP) – Jesse James, the celebrity motorcycle builder and reality-TV star, is a "a broken man" and is hoping that rehabilitation and some privacy will help him recover and save his marriage to actress Sandra Bullock, his friend and attorney said.

Joe Yanny said that allegations of marital infidelity against James and the ensuing media "feeding frenzy" have ruined the biker businessman's life.

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

He said James is still in love with Bullock and hopes the marriage can be saved.

James checked into a rehabilitation centre after weeks of reports that he cheated on Bullock throughout their marriage. Yanny declined to say what James is being treated for, but said people shouldn't assume it is for sex addiction. He also wouldn't rebut specific allegations lodged against the West Coast Choppers owner or say whether there are plans for the couple to get a divorce.

"The allegations back and forth about what happened – those are private matters to be resolved between a husband and a wife," Yanny said. "It's not appropriate for a public airing."

He said the vast majority of stories about James are untrue.

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

James and his camp have said little since a woman told In Touch magazine that she carried on an affair with James while Bullock was shooting the blockbuster hit 'The Blind Side'.

The film earned Bullock widespread acclaim that culminated with a best actress Oscar. Within days of her win, the cheating allegations broke and Bullock withdrew from the public eye.

James released a statement saying he had used "poor judgment" and deserved "everything bad that is coming my way."

Bullock has not spoken publicly about the matter, and her publicist did not respond to e-mailed questions for this story. Public support for the actress has remained high as more women have stepped forward claiming they had affairs with James in recent years.
