The glamour model explained to Digital Spy that although she wouldn't return to the ITV2 show now, she could certainly see herself coming back for a reunion special.
"I've always said never say never with TOWIE," she said. "You never know, if it comes back in ten years again, I could be going back on it.
"TOWIE's a good show. I wouldn't go back on it now, but maybe one day the [ex-cast] of TOWIE could come back and I'll be one of them."
Childs also confirmed that she is filming "a project" with cousin and ex-TOWIE star Harry Derbidge, thought to be a remake of Paris Hilton and Nicole Richie format The Simple Life, to air next month.

On the success enjoyed by herself and other members of TOWIE, she added: "I think that we've proved to everybody that we've done well from being in a reality TV programme.
"We've worked hard. It's not been given to us. All the haters, I think they're just a bit jel."
Childs was speaking at the Nature Valley Games, where she helped Nature Valley - official supplier and sponsor of the London 2012 Olympic Games - bring the country to the capital.
