Sorry Lee Ryan, Duncan James says he never had sex with you - and he doesn't intend to anytime soon, either!
"I've never even touched Lee's willy and that's the truth"
Duncan denied the claims to a national newspaper, saying: "I've never even touched Lee's willy and that's the truth. I've seen it, but I've never touched it.
"He's like my little brother. It would be like incest if I slept with Lee Ryan."
He added: "Hand on my heart, on my daughter's life, I've slept with him in the same bed, but I've never actually physically had sex with him."
The outburst comes after Lee "admitted" on Celebrity Big Brother that he'd had sex with a man, telling his housemates: "Everyone has done experimental s**t, I am a well travelled person."
Lee then later said he has sex with his his Blue bandmate "all the time".
Duncan has his own theory as to why Lee would lie about their relationship - and it has a lot to do with Jasmine Waltz:
"I think Lee's just trying to impress Jasmine if I'm honest," he admitted.
"He's trying to say things to shock her because I think he genuinely really likes her. He wants her to think he's really out there, different and cool."
Despite Lee's fibs, Duncan still has a soft spot for his Blue bestie, saying Jasmine would have him to deal with if she broke Lee's heart.
"I hope that she's got Lee's best interests at heart, because if she hasn't she's got me to deal with."
