Bookie ups odds of Kris, Sophie romp

What happened between Kris and Sophie under the covers last week has caught the attention of a British bookmaker.

Paddy Power has fuelled rumours that the pair had sex after offering odds of 8/11 that intercourse took place.

A show source said: "There was a lot of fumbling under the sheets and Sophie was clearly enjoying herself with Kris, but no-one really knows yet if they had sex."

Kris and Sophie sparked speculation of a tryst after kissing and cuddling in the bedroom.

The housemates later disappeared under the sheets, but the Big Brother cameras did not capture what did or did not happen before they fell asleep in each other's arms.
