Kris Smith has admitted that his insecurities from being a 'fat kid' may have instigated the breakdown of his past relationships.
On February 5 episode of the reality TV show, Kris was asked about his dating life by fellow star Natalie Bassingthwaighte.
"Do you know what, I think I've ruined a lot of them," the 38-year-old admitted.
"[I was] just insecure and jealous. Not anymore, [but] I was because I was insecure - I never believed I was good enough."
I was really short and heavy as a kid. I always still see that. With age and growing up, I always had that little demon in my head that I was still that little fat kid.'
"It's probably ruined a lot of my relationships, I was insecure with people I was jealous of what they did and what they said," he admitted.
"I never valued myself and never thought I was good enough for anyone."
Smith was welcomed by Australian fans when he began dating Danni Minogue in 2008. The two share a young son Ethan and remain amicable.
After his breakup with Minogue, he began dating model King, but the two ended their relationship in late 2016 after two years together.
