The singer was recently criticised for his foul language and crude gestures while speaking in between songs during his five-track solo segment of the tour. However, he insisted that he has no intention of changing his ways.
"I was born and raised for the first three years of my life in a pub," Williams told The Sun.
"One of my first words was f**k and one of my first sentences was, 'Give me a f**king Harvey Wallbanger, please'. I didn't get one."
Williams also addressed the 85,000-strong crowd during Take That's show at Wembley Stadium on Friday night, declaring: "I really apologise for all the swearing. There's a number you can ring to complain. It is 0800 go f**k yourself."
The 37-year-old has faced a number of comical issues during his reunion shows with Take That, including splitting his trousers on one date and accidentally flashing members of the audience at another.
