Serial cheater Jesse James reportedly bolted from a sex-addition clinic after his Oscar-winning wife refused to take his phone call, the New York Post reported Monday.

An angry James checked out of the Sierra Tucson treatment center in Arizona because Sandra Bullock, on whom he cheated with several women, apparently wants nothing more to do with him.

"He wants the marriage back," a source told RadarOnline. "And then she refused to take one of his calls from the rehab center and he got furious and left."
