British pop star Lee Ryan's representative have dismissed allegations he cheated on his model ex with a guy.
Jasmine Waltz claims her romance with the former Blue singer, which began when they were contestants on U.K. reality show Celebrity Big Brother, came to an end when she learned of his infidelity.
She took to Twitter.com on Tuesday (01Apr14) and wrote: "The minute I got home to L.A., he cheated on me with a Man! #admitUgay."
Waltz followed up the tweet, which has since been removed, by insisting it wasn't part of an April Fools' Day prank.
She added, "Wish this was a joke. Living a lie and dragging other ppl (people) into your life is selfish and disgusting."
But a spokesperson for Lee has dismissed her allegations, insisting they are absurd.
The rep tells MailOnline.com, "We will not be commenting on the absurd claims made today. We wish Jasmine the best in her future endeavours.
"Lee was kind enough to welcome Jasmine to stay at his home when she told him that she didn't have anywhere else to stay in the U.K. Lee's first and foremost priority is the wellbeing of his children and anything or anybody else comes secondary to that.
"Lee could not travel out to America as much as Jasmine would have liked him too, due to his commitments in the U.K. He hopes Jasmine finds what she is looking for and wishes her the greatest happiness and success in her aspiring acting career."
But Waltz is refusing to back down. In a final tweet on the matter sent late on Tuesday, she wrote, "It always comes out In the end..."
Lee and bisexual former bandmate Duncan James previously denied reports of a relationship.
James said, "He's like my little brother. It would be like incest if I slept with Lee. I've slept with him in the same bed, but I've never actually physically had sex with him."
