The 'Blue' star was recently accused of cheating by his ex-girlfriend - whom he met in the 'Celebrity Big Brother' house earlier this year - who claims he betrayed her for a man, but he now appears to have denied the accusations with a number of Twitter posts.
He posted a picture of a grinning horse alongside a caption which read: "hahaha...This is exactly what I'm doing right now! Lol...Laugh and the world laughs 2 (sic)."
The 'One Love' hitmaker also hinted that his relationship with the model - which developed on the reality show after he was criticised for leading glamour model Casey Batchelor on - had been a mistake when he posted another image with a picture of a Buddha statue with the quote "No matter how hard the past you can always begin again."
Lee then added: "very true...Life is made for mistakes. How else would you learn and grow? (sic)"
Jasmine - who developed a close friendship with former 'Apprentice' star Luisa Zissman on the Channel 5 show - sold a tell-all interview last month in which she slammed her ex-boyfriend, but she later took to Twitter to reveal the "truth" behind their split.
She wrote: "Unfortunately the Sun failed to mention the real reason ... which was that the minute I got home to LA, he cheated on me with a MAN! #admitUgay (sic)."
