Jerry Hall is coming clean about her tumultuous, 23-year relationship with Mick Jagger.

In a revealing new interview, the 59-year-old former model confessed she once had an affair a man named Robert Sangster to seek revenge on her partner Mick, 72, after she found out he was cheating on her with Italian model Carla Bruni.

"I did [want revenge]. At one point I went off and had an affair with somebody else. Robert Sangster. So lovely. Horse breeder. Then Mick would beg me back," she told the Radio Times.

"I thought Mick would eventually change, but he didn't… I mean he's Mick Jagger and millions of girls throw themselves at him, and he's in the position where he says yes," she added.
