'Apprentice' star Jordan Poulton said that while he and Luisa Zissman were on the reality show, they had sex multiple times.
The saucy couple were always sneaking away from their minders while filming the BBC One business programme, but Jordan insists it was the 26-year-old beauty that initiated the steamy sessions.
He said: "When I was with Luisa I spent a lot of time in cupboards -- literally.
"It wasn't easy to have sex in the 'Apprentice' house as there were minders living there trying to stop us.
"She made no secret of how sexual she was. Right from the start she told me all about her exes and the sex parties that she'd been to."
Luisa is currently starring on 'Celebrity Big Brother', where viewers saw her drag Dappy into the shower with her at the weekend.
However, the star's naughty antics haven't come as a surprise to Jordan as he admits she always has "sexual tension with somebody".
He explained to The Sun newspaper: "Luisa has always got sexual tension with somebody. Our routine was I'd go off somewhere and she'd disappear too, and we'd muck around until someone came to find us.
"When people try to stop you having sex, the tension ramps up more."
Jordan insists his sexual relationship with Luisa ended when the 'Apprentice' ended last year, but he's confident they're still friends.
