Robbie Williams is said to have offered his former Take That bandmate Mark Owen his LA mansion after the latter's wife threw him out over his womanising.
Williams, 36, said Owen, 38, could use his Los Angeles home for himself or as a place where he could go with his wife, Emma, 33, to talk through their problems.
"Mark has confessed to having issues with booze and with his own substance abuse past," the Daily Star quoted a source as saying.
"Robbie is the perfect person to offer him support," the source added.
Owen, who has children Elwood, three, and Willow Rose, one, with Emma, swore that he had been faithful to her since their wedding five months ago.
"You loved me and I've let you down. I'm sorry," he said.
"I'm so deeply sorry for the pain my actions have caused my family and friends.
"I'd like to ask the media to please respect the privacy of my wife and children during this difficult time," he stated.
