George Michael to write Spice Girls hit?

George Michael has been approached to write a Christmas single for the Spice Girls, according to a report.

The group's manager Simon Fuller has started making plans for the singers to take on the X Factor winner in a Christmas chart battle.

An insider told the News of the World: "The girls are thrilled to be in talks with George. He's one of the most talented songwriters around and it will make their comeback bigger and better than ever."

The source added: "This year's Christmas No1 is a two-horse race and is impossible to call. The X Factor looks unstoppable, and the show's been getting some really good ratings too."

The girls had three consecutive Christmas number ones in their heyday; '2 Become 1' in 1996, 'Too Much' in 1997, and 'Goodbye' in 1998.
