Robbie Williams was flashed on stage during the first night of his tour at London's O2 arena at the weekend, according to reports.
The father-of-four, 48, was mid song when a lady lifted up her top in the audience - much to the singer's surprise.
The Take That star, who is married to Ayda Field, is reported as saying: “There is a lady here getting her breasts out for me down here.
“Incredible. Total scenes.
“But for me, it is like being a diabetic in a cake shop. There’s nothing I can do about it, is there?”
To celebrate 25 years as a solo artist, Robbie is back with his epic XXV tour, performing at venues including London’s O2 and the AO Arena in Manchester.
While on stage at the weekend, the star reflected on his exit from Take That, saying: "they couldn't contain me anymore".
The singer was engaged in a rift with Gary Barlow over who sang lead vocals, which started at the beginning of the group’s super successful career
“It’s a 32-year musical odyssey,” Robbie told the audience at London’s O2. “The highest of highs, the lowest of lows. The drugs, the sex, the scandal... the meat pies.”
Discussing his decision to quit the group in 1995, he continued: “I started getting ideas about writing my own songs.
“One thing led to another and I made the cardinal mistake of breaking the rules. They couldn’t contain me anymore."
The star now is now working with Netflix on a new documentary, which promises will offer a microscopic look at his life.
While filming for the much-hyped film is yet to begin, Robbie has teased fans with what to expect when cameras do start rolling at his Kensington mansion in London.
The Rock DJ singer has editorial control over the content and claims this will make it even better viewing as he won't shy away from baring his soul.
He told New Zealand radio station Newstalk ZB's The Mike Hosking Breakfast show: "It’ll be full of sex and drugs and mental illness.
"They haven’t started. I’m sure it will be warts-and-all, and I’m sure it will be me giving away too much information about my life and times. I’m looking forward to getting it started and finding out what it is myself."
The star continued: "I’m more likely than most people to leave everything in, I very rarely, if ever, have said, ‘That’s too much, take it off.’ I normally think that it’s not enough."
