Singer Lee, 30, has had us glued to our TV screens ever since he entered the Celebrity Big Brother house last Friday (3 January) and yesterday was no different.
During a late night chat with housemates Ollie Locke, Luisa Zissman and love-interest Jasmine Waltz, Lee admitted for the first time that he has previously been "experimental" in the bedroom.
He said: "Yeah I've been with a man. Everyone's done experimentational s***.
"I'm a well-travelled person. I've never admitted it anywhere. No-one's bothered to ask."
Lee's bisexual bandmate Duncan then tweeted: "Oi @LeeRyanMusic I though I was the only "bi/gay" one in the band! Lmao #jumpingOnTheBandWagon".
Duncan came out as bisexual back in 2009 and has also referred to himself as "gay" in several interviews, including one last year in which he revealed his struggle with his sexuality.
Speaking to the Mirror last May, Duncan explained that he'd felt guilty for sleeping with men because of his Catholic religion.
"It was a really hard thing for me to do, to explain I was gay and sleeping with guys," he said. "Obviously, this goes against everything the Catholic Church stands for."
The 35-year-old has been showing plenty of support for pal Lee on Twitter this week and has defended his bandmate's controversial behaviour in the CBB house with Jasmine and glamour model Casey Batchelor.
