Duncan James has dismissed claims that he enjoyed a gay fling with Blue bandmate Lee Ryan.
Lee, 30, admitted during a chat with Celebrity Big Brother housemates Jasmine Waltz and Luisa Zissman that he had "been with a man".
Newspapers later alleged that the Blue singer had "been intimate" with his pal.
But bisexual Duncan - who has previously admitted to having threesomes with Lee - dismissed the suggestions.
According to MailOnline, Duncan tweeted: "Still laughin at this mornings claims. Every1 knows about the 3somes but its never gone beyond that. I mean I love Lee but not THAT much."
Lee reportedly told Now magazine in 2010 : "Me and Duncan had threesomes! We did some crazy s**t with each other. And I'm a bit camp sometimes."
