The openly bisexual singer revealed on the ITV show: ‘Michelle Heaton turned me gay’, referring to a fling the two had during their time on the road with their bands Liberty X and Blue during the early 2000s.
And it seems Michelle wasn’t best pleased with his claims.
Duncan said: ‘You know what, she got really upset at me for saying that. I mean, bless Michelle. I love her to bits, but she does love a bit of a drama.
‘She said,”People are actually going to think that is the case, Duncan.”
‘It was a joke! She’s over it now though.’
Better watch what you say next time Dunc!
