Essex, 21, insisted that fellow TOWIE star Wright is only "flirting" with the model, who previously dated Little Britain star David Walliams.
When asked by Heat whether he believes the pair's fling will continue, he responded: "No. They're in the jungle for a little while, aren't they?
"But after that, they won't see each other much. He's just flirting with girls because that's what any Essex boy would do - just flirt with a girl and then… 'See you later!'"
