The 61-year-old Rolling Stones guitarist – who has been having an affair with 20-year-old Russian waitress Ekaterina Ivanova – reportedly confessed his feelings for wife Jo, 52, and his young mistress to fellow patients at a rehab facility.
He said: "I love my wife - but I have a girlfriend and I love her too."
The aging rocker is being treated at a countryside retreat for alcohol, drug and sex addiction.
A source said: "He is being treated for everything. He isn't allowed a phone or any contact with the outside world for now."
"He is having open therapy sessions and explained he has a wife and a girlfriend and that he loves them both."
"It's very strange but it's just how he sees it. He's looking a lot better and is very upbeat."
Staff told Ronnie he must complete a six-week treatment program after hearing of his vodka binges, his 20-year-old lover and previous drug problems.
The source added to Britain's The Sun newspaper: "He thinks the whole affair scenario has been blown out of proportion – but that's part of his problem."
