The X Factor singer, who is gay, told Now that he would not rule out having sex with a woman in order to have a child, but also said he could adopt.

"I can't wait to have kids - I do want babies and I want them the right way," Clark said.
"I've never been with a girl. It's not my thing but I'm not ruling it out. I'm not sure about surrogacy. I don't know how I'll do it but it will be done."
He added: "Just because I'm gay, I can still come! And if I can't have kids, I'll adopt.
"What's to stop me having kids? Nothing. I want the Range Rover, the husband and two kids. I want to take my boy to football on a Sunday and my little girl dancing on a Wednesday."
The singer revealed that he has been single for three years after the break-up of a serious relationship.
"The gay world can be promiscuous - a lot of men want to f**k you then chuck you," he said. "But that's not what I'm about."
Clark was eliminated from The X Factor this weekend after the judges voted three-to-one to send him home when he finished in the bottom two alongside Union J.
