Paris Hilton is launching her own brand of champagne and has decided to donate a percentage of the profits to charity. The socialite will give 20 per cent of the money made from the Rich Pressco line to a charity which provides fresh drinking water to people in need, according to celebrity blogger Perez Hilton. Hilton, who was convicted of DUI earlier this year (07), has been promoting her new business venture with a raunchy photoshoot featuring the Simple Life star posing naked and covered in gold body paint.
