Luisa has been open about her love of women in the past, even saying in her introduction VT upon entering the house: "I’m very open to exploring my sexuality. I think it’s good to be a sexually empowered woman.
"I love girls, but I wouldn’t have a relationship with a girl. I’ve been with both guys and girls," she added.
It was reported that she ended her relationship with DJ Greg Burns to enter the Big Brother house as a single girl.
He has since been spotted on a date with Spice Girl Mel C.
