Big Brother Kris Explains How to Tell if a Lad is Under the Thumb

Big Brother Kris has his own theory on how to tell whether a lad is under the thumb. He reckons that if a guy has changed his mobile's screensaver to that of his girlfriend, then he's under the thumb. Kris says he never changes his from a picture of the lads. We'll have to see whether fellow contestant Sophie manages to get him under the thumb, as she and Kris have been getting closer since first getting together in the pool over the weekend.
