The singer was dancing during a concert held in Croke Park, Dublin, on Saturday when he accidentally showed his pe#!s during a routine of the song “Rock DJ”.
“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,” a fan who was at the concert told The Sun.
“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,” the same fan added.
This is not the first time Williams makes such a gesture.
In 1999, he appeared naked on stage during a show in Atlanta, Georgia, and in January this year, he filmed a Happy Birthday! message for his band mate Gary Barlow nude. Last week, Robbie Williams ripped his pants during a concert at the stadium in Cardiff, Wales, and cried: “I’m so excited I’ve split my keks!”
