At leas that's according to her fellow housemates, with Lee Ryan and Sam Faiers talking about Luisa and Dappy in tonight's show.
And they reckon there's some definite sexual tension going on between the pair.
Lee say: “I’m like get a room, just hurry up get it over and done with.”
Sam agrees: “That’s what I said, I said to her the other day I said you fancy Dappy.”
Lee signs: “She does, she wants his Dappy d**k. Dappy’s d**k, Dappy’s d**k, Dappy’s Dappy’s di**k. She wants it.”
Luisa told her fellow housemates just this week that she was craving sex in the house.
"I can’t stay in here much longer and not have sex. I’m really struggling,” she admitted.
Luisa’s sex life has been a big topic in the house, having previously told the other celebs: “Sex is something to be explored. It’s really good. It feels nice.
“If you want to go to a sex party and have a massive gangbang, then cool.”
And earlier this week, Dappy and Luisa got closer than ever as the N-Dubz star surprised the Apprentice star with his penis.
Dappy boasted to her: “Hey Lulu, I have something for you. Dong, dong, dong dong.”
Luisa reacted: “Your willy is so big. Are you a shower of a grower? Does it grow much? What would you do if you didn’t have a big one?”
Dappy replied: “I’d be upset.”
