Matt Cardle has addressed claims made by a former girlfriend that he was unfaithful during their relationship.
According to Now, the X Factor Winner said: "I admit I was unfaithful, which is bad.
"Ultimately, what I want is a relationship where I won't be unfaithful. I think my problem may be that I've never had my heart broken."
The 27-year-old, dated Lauren Cutmore for two years, but the pair split after Cardle made it through to the boot camp stage of the show.
He decided that he didn't have time for both the talent programme and a relationship.
However, despite beating Rebecca Ferguson, 24, in the show's final, and reaching No 1 in the charts with his debut single 'When We Collide', Cardle remains wary of his legion of female fans.
He said: "I've definitely changed when it comes to women.
"A few months ago I'd have been loving all the attention, but I'm a bit scared off now. It's been a wake-up call."
