Karren is a guest on Jonathan Ross's chat show this weekend where she explains it's fortunate Lord Sugar is currently in America so hasn't witnessed Luisa's frank confessions about sex parties, sex addiction and kisses with fellow housemate Jasmine Waltz.
Luisa, 27, came second to doctor Leah Totten in the last BBC series on her "business merits", but in the Big Brother house she has spent more time enjoying herself than talking revenues.
“I think she has mapped out what she wants to do with her life and that’s part of it. The thing is if you’re in television you can get addicted to being in television and you want to do one thing and another thing and before you know it, all you are is a television celebrity,” she added.
The Blue singer told the story as he and Luisa discussed their sexual antics with fellow bisexuals Jasmine Waltz and Ollie Locke in the garden.
"Yeah, I’ve been with a man. Everyone’s done experimental s***," he told them.
"I’m a well-travelled person," he added. "I’ve never admitted it anywhere. No one’s bothered to ask."
Delighted by all of her housemates’ confessionals, Luisa added, "I love an orgy."
