Boy George's relationship with Jon Moss is a ''mystery''.
The 'Karma Chameleon' hitmaker thinks it is ''weird'' that there is no longer any ''proof'' he and his Culture Club bandmate - who has three children with ex-wife Barbara, who he split from in 2010 - were romantically involved until 1986, but insisted they are still close.
He said: ''Our relationship is like a mystery. It's like, we know it happened, but there's not really proof anymore, it's kind of weird. We're really good friends now.''
The 52-year-old star is proud of the fact he has remained friends with many of his ex-lovers, and admits he is now closer to some of his former flames than when they were in relationships.
Speaking to 'Access Hollywood Live', he said: ''One of the great things is when you can grow up a bit and then of sort of be friends with the people you went out with. I have like three or four ex-lovers that I'm really good friends with and I'm probably better friends with them, now that we're not lovers, than we were when we were together.''
He explained: ''[Justin Bieber] is gorgeous! ... I was in the store the other day and I was looking at Miley Cyrus and I was thinking, actually she has a kind of androgyny about her and similarly does Justin Bieber. And I think some of the biggest kind of stars have that kind of boy-girl thing.''
The actress thinks it would be tough to recast her character, Winifred Sanderson.
