Williams, 36, who is about to release his first single with Take That after 15 years, said he has developed a passion for art.
According to UK newspaper the Daily Star Sunday, he said: 'I've turned my garage into an art studio and have done six paintings in the last two weeks. A gallery has even offered to buy some.”
He added: 'It gives me the same buzz as music, especially when you've spent all day on it. I'm strictly into abstract at the minute because I'm not talented.
“But you know how you walk past a painting and go, 'I could f****** do that?' Well, I'm actually f****** doing it.'
