The Rolling Stones legend Bill Wyman has admitted he was "really stupid" to think marrying Mandy Smith when she was just 18 would work.
The bass guitarist, now 82, has told of his regret at the marriage because of the 34-year age gap.
Mandy was still a teenager when she became Bill's second wife in 1989 - he was then 52.
But the couple separated two years later and finalised their divorce in the early 1990s.
"It was from the heart. It wasn’t lust, which people were seeing it as," Bill said.
"I was really stupid to ever think it could possibly work. She was too young. I felt she had to go out and see life for a bit."
The father-of-four, who was born in Lewisham, southeast London, made the confession in the documentary The Quiet One, which premiered at the Tribeca Film Festival on Thursday night.
He defends his relationship with Mandy in the film but admits she was "too young".
Wyman, who was one of the founding members of the iconic rock group, first met Mandy in London in the mid-80s when she was 13.
They married when Mandy reached the legal age of 18.
The Quiet One is written and directed by British filmmaker Oliver Murray and features footage and photos from Wyman's years with the Stones.

But the documentary has been pulled from England’s Sheffield Doc/Fest next month because of the rocker's scandalous relationship with Mandy.
Bill has since gone on to enjoy a third marriage, with actress Suzanne Accosta. The couple have three daughters and live together near Bury St Edmunds, Suffolk.
The rocker gushes about Suzanne in the new documentary.
He also touches on his family life growing up in working class London.
The film explores how Bill's father cut short his education by making him leave school to work for a bookie to help support the family.
Bill, who was one of the founding members of the iconic rock group, was part of the Rolling Stone's line-up from 1962-1993.
