The 45-year-old former Culture Club head details his affinity for gay prostitutes and his history of cocaine use, all amidst a torrent of negative comments about the popular singers, The Independent reports.
"Madonna... I just think she's a vile, hideous, horrible human being with no redeeming qualities," George said of the U.S. pop singer. "There's nothing nice about her."
"He could use my help; the last album was terrible," George said of Williams. "He's at that point now where he's just throwing anything out -- he needs another 'Angels' or something really classy. That new thing he's got out, it makes Ronan Keating look like a genius."
The entire length of the documentary, entitled "The Madness of Boy George," will be available during a screening this Tuesday, The Independent said.
