Leandro Penna would "never" go back to Katie Price because she is "empty inside".
The Argentinean model first started dating the 34-year-old star in February 2011, before breaking up last month, and he has revealed he could not get back together with her - despite her wanting him to - because he feels he never knew "the real" her.
He said: "Leaving her was the best decision I ever made. She was still messaging me two weeks ago, begging me to come back, but I'm never going back and I've told her to leave me alone.
"I feel Katie tricked me into leaving my life in Argentina. She saw our relationship as a business and she loves being famous. She made a lot of money out of me with her reality show and by selling pictures and interviews. Inside, she's empty."
Leandro also reveals Katie is "self-obsessed" and always gets angry about Victoria Beckham's lifestyle as soccer player David Beckham's wife because it is something she can never have.
He told Reveal magazine: "She spends morning, noon and night looking at pictures of herself online - she is self-obsessed.
"Katie is very jealous of all WAGs because she sees their lifestyle as safe - whereas she doesn't feel safe.
"Victoria Beckham makes her very angry. She's jealous of her friend Danielle Lloyd and says things like, 'Her husband gave her a Bentley.' "
