UPDATE 1 PM EST MONDAY:
Radar reports that James checked back into rehab after a few days AWOL.
A week after checking into an Arizona rehab facility, multiple reports say Jesse James has checked right back out. He was going to be there 45 days, according to outlets.
Radar reports that he left when estranged wife Sandra Bullock wouldn't take his phone call as part of group therapy on Sunday:
Jesse desperately wants to put the marriage back together and his lawyer recently described him as a "broken man." He went into rehab for sex addiction treatment
on his own, without Sandra requesting he get help.
But when she refused to take his call, he took off, a source familiar with the situation told RadarOnline.com exclusively.
Star Magazine has a similar story:
A source close to Sandra Bullock's disgraced husband, Jesse James, tells Star that the West Coast Chopper hunk has left rehab after only one week, and is laying low at a male friend's house.
The source claims Jesse quietly checked out of Arizona's Sierra Tucson Treatment Center within the last couple of days. His exit coincides with a moving van being spotted outside the Seal Beach, Calif., home he has shared with Sandra on April 2.
