Cheryl Cole has shown once again that she is queen of celebrity looks, topping Tatler magazine's best dressed list of 2009.The Girls Aloud singer has reached mega stardom following her stint as a judge on the X Factor and a spokesperson for the magazine said: "The world has gone completely insane for our Cheryl."Former top ten entries Kate Moss, Agyness Deyn and Alexa Chung did not make this year's list and Cheryl came ahead of model Claudia Schiffer and actress Natalie Portman.Her profile has been further raised by her recent efforts for charity as she and bandmate Kimberley Walsh joined seven other celebrities climbing Kilimanjaro in aid of Comic Relief.She was one of the first of the team to reach the summit of the 5,900 metre peak, along with Fearne Cotton, Denise Van Outen and Ben Shephard.Kimberley, Ronan Keating and Gary Barlow were in the next group to make it to the top while Chris Moyles and Alesha Dixon were the last up.The group has raised £1.4 million for charity.(c) 2008 Adfero Ltd.
