Oh yeah I think she IS on this! I think it's her who is on the stage from 2.25 minutes in - to about 2.50 minutes. (Shoulder length straight blonde hair.) So I think (like Farida) she is attention seeking and fame hungry.
Problem is with Kerry and Farida, they clashed terribly, because they were one and the same. Cut from the same cloth. There was only room for one person like that in the BB house.
Here's the Adele sketch with KERRY in it. Give it a watch! You will spot Kerry pretty quickly.
(And it's a funny sketch anyway, and well worth watching.)
