The Big Brother housemates have bared all, confessing which of their fellow contestants they would like to sleep with.

Birthday girl Mary stunned the housemates when she was asked which of the men she would most like to have sex with by saying she would have a threesome.

During a boozy game of truth and dare Mary said: "I'd choose a threesome and add some girls in there for a bit of fun,"

When asked to name the girls she said "all of them" and added that she fancied the idea of all the housemates together in one bed.

The 30-year-old white witch then went on to reveal her feelings about the men and left Science, 22, speechless by saying: "I think Science is sexy and I'd definitely put him in the sack."

She said she had more of a "spiritual connection" with Liverpudlian Roberto, 32, and added she was just "good mates" with Maxwell.

Earlier on Maxwell, Anthony and Vanessa discussed whether they were prepared to have sex while in the house, with the first two declaring that they would.

Maxwell bragged that that he would "go like a train for an hour and a half" in full view given the chance, only for Anthony, a 23-year-old 70s dancer, to claim he too could go that distance.

Vanessa, 19, left them guessing as she said: "Maybe... you'll have to find out for yourself."

Meanwhile Roberto's nail varnish sparked a discussion about vanity but he insisted he had no problem with his image.
