Los Angeles - Robbie Williams
accidentally flashed his penis to 82 300 fans.
The Take That star was performing his solo section at the group's concert at Croke Park in Dublin, Ireland, on Saturday when his penis popped out of his trousers during a raunchy routine of Rock DJ.
An onlooker told The Sun newspaper: "It was a pretty wild routine so it's no wonder it fell out. He didn't seem in a hurry to put it away.
"He was definitely up for it. He was going mental, shouting and swearing, trying to get the crowd going before shoving his hands down his trousers. Even though he was like a man possessed, the ladies didn't complain." Birthday message
This is not the first time Williams - who rejoined the group last year, 15 years after quitting to launch a solo career - has exposed himself.
In 1999, he walked on stage naked during a show in Atlanta, Georgia, and in January he filmed a birthday message for bandmate Gary Barlow's 40th birthday completely nude.
Last week, Robbie ripped his trousers while on stage at Cardiff's Millennium Stadium in Wales and yelled at the thrilled crowd: "I'm so excited I've split my keks (British slang for trousers)!"
