Cleo is best known for her work with Kenny Everett on his legendary radio and television shows. She became Miss Whiplash of his BBC1 show in the early 80s. Cleo and Kenny enjoyed a 15-year friendship until his tragic death in 1995.
More recently Cleo has performed with Leigh Francis in sketches for his Channel 4 series "Bo In The U.S.A", and produced "The Seven Year Itch" in the West End. She is currently writing a new comedy series.
Cleo was once kidnapped in Buenos Aires and counts Darryl Hannah and Robbie Williams amongst her famous friends. She lives with her mother, loves to eat Mexican salsa for breakfast and has a pet parrot called Max.
She said: "It (BB) used to scare me a bit, but I've become addicted to it over the past couple of years. It's dangerous and unpredictable and I think I'll have a lot of fun in there. I like throwing all the saucepans in the air.
"Nobody I know would ever think I'd do something like this. I'm not a good sharer, I'll probably be the most neurotically private person in there. But I push myself: I've trained with matadors and I don't think you should play anything too safe."
