Celebrity stylist Ken Paves has called on celebrity clients like Brad Pitt, Christina Aguilera, JESSA SIMPSON and Eva Longoria PARKER to help him raise a fortune for charity. The generous hairdresser has asked his famous friends to donate memorabilia items for a `Big Give' auction he's planning online. Victoria and David Beckham, Bette Midler, Courteney Cox and Carmen Electra are also among those who have handed over items to Paves for his eBay.com auction, which has been launched in connection with Oprah Winfrey's Big Give U.S. TV show. All proceeds from the online auction, which runs until 7 April (08), go to children's charity the EB Medical Research Foundation.
