Hollywood stars George Clooney and Johnny Depp's requests to appear in the upcoming series of UK comedy show LITTLE BRITAIN have been snubbed - because they are too famous.

David Walliams and Matt Lucas, creators and stars of the highly acclaimed sketch show, have no intention of following Ricky Gervais' example by writing celebrity cameos into their sketches.

THE OFFICE star Gervais has been grabbing headlines after announcing he has signed up Tom Cruise for an appearance in his show EXTRAS - but Lucas and Walliams can't imagine their comic creations interacting with hunky superstars.

Lucas says, "It could really unbalance the show. I mean, (our characters) LOU and ANDY would never meet George Clooney.

"There will be no cameos from the stratospherically famous. We try to save celebrity appearances for (British fundraising TV extravaganza) Comic Relief."

SIR Elton John and British singer Robbie Williams made brief appearances in Little Britain's Comic Relief DVD which raised $3.6 million (GBP2 million) for the charity.
