I was wondering who this Karen person is, but i've just been informed she's one of BB staff.
The video of Akeem threatening to "knock Karen out" exists apparently - Lewis G tells Akeem he knows the room where the "girls" are and Akeem says "What girls?" Lewis says "plenty" and Akeem says "go get them". Lewis G asks him "do you want me to get the girls" Akeem says yes.
Lewis G then leaves the room and sees Zoe in the corridor and talks to her and Karen ( they are off camera). Then he goes back to Akeem and says "mate there's staff everywhere, I mean everywhere, we'll have to wait til they're asleep. They're all over, I've seen Zo Zo and Karen" Akeem says "Cameron?" Lewis says "no, KAREN", Akeem says "oh well, I'll knock her out". At this point Lewis collapses on the bed in a fit of giggles saying "he said, he said, he said he's gonna knock her out" he's laughing his head off and Akeem repeats "I will, I'll knock her out".
How lovely!
