She did have sex in the house with Kris, not that you would ever know because she has not had any hysterical forum/press backlash - she must have a good agent.
I doubt she is pregnant form any sex activity she indulged in with Kris in the BB house, because she would not show that soon. She is putting the weight on like most of the BB female housemates always do, to their horror.
The females usually stuff their faces all day/night because of the stress/boredom, and you must remember outside the house they live on carrots and fresh air so any weight gain will be seen pretty quickly.
