Kem Cetinay regrets betraying Amber Davies on "Love Island".
The 21-year-old hairdresser and his 20-year-old girlfriend were crowned the winners of the ITV2 show with a whopping £50,000 prize this week and Kem admits he is still upset that he almost threw away the relationship for a fling with Chyna Ellis, even though they were on a break at the time.
He told The Sun: "It was such a big moment. What happened was the biggest regret for me.
"I hate that I snogged Chyna. It is still hard for me to hear.
"I don't like talking about it because it genuinely makes me feel sick. I hate it.
"Amber felt like I weren't interested in her, that's why she kept her options open.
"My way of dealing with feelings is putting it on someone else."
However, he blamed the indiscretion on his feelings of vulnerability.
Kem said: "I was so not in control of the situation and was pushing everything away. It was my way of dealing with not knowing what was going on.
"Mine and Amber's issue is that we are both so scared of being vulnerable in a serious relationship.
"When you're young and in a relationship you're always going to learn and make mistakes."
Meanwhile, Kem and Amber were over the moon when they were announced as the winners of the show earlier this week, but bosses decided to put their relationship to the test almost immediately as both of them had to pick an envelope - one containing the prize money and the other was empty - and whoever won the cash could either keep it for themselves or share it with their partner.
After having the grace to let Amber pick her envelope first, it was Kem who managed to bag the cash, and after an audience member told him to share the money with his pal Chris, the hunk decided to honour his girlfriend by splitting the funds with her.
He said: "Of course I'm going to share it".
