George Michael to appear in Ricky Gervais' Extras?

British pop singer George Michael is reportedly in talks to appear in the last ever episode of Ricky Gervais' sitcom Extras.

The former Wham! singer will apparently be appearing in the one-off Christmas special, which follows the first and second seasons last year.

A source tells British tabloid newspaper 'The Daily Star'; "George immediately agreed to appear on Extras. It's going to be absolute dynamite.

In a recent interview, Gervais revealed: "I have got a bottle of champagne in the fridge - and beat this - it's from George Michael. He gave me it after I supposedly called him a bender at an awards ceremony, if you believe what you read in the press. It was actually part of a joke that I ran by him first that he loved."
