But, while in an interview with music channel MTV in the US, he has put an end to the speculation, by saying: "If people want to say that, they can. I''m not. I''m straight."
He added: "My favourite thing I saw was a guy on the internet who said, Of course he's gay - he's got a gay face, which I thought was kind of an odd thing to say anyway. A gay face? That's a very worrying thing, like they have sat at home with pictures of me next to other famous gay folks."
Daniel is reported to have recently made a "major donation" to an American charity that fights intolerance of gay men, lesbians and bisexuals. In a past interview, he said: "Some people think I am gay, which I think is awesome."
