KELLY OSBOURNE - STARS UNITE AT PEREZ HILTON'S PARTY

British pop royalty met young Hollywood royalty on Friday night (23MAR07) when KELLY OSBOURNE and AMY WINEHOUSE partied with Hiltons PARIS and PEREZ. Internet gossip king Perez Hilton - real name MARIO LAVANDERIA - dyed his hair sky blue for his 29th birthday bash at the Roxy Theatre in West Hollywood and welcomed three of the world's leading party girls, who were among the first to arrive. Osbourne and UK diva Winehouse, who cancelled a Los Angeles show on Tuesday night (20MAR07), turned up together and were soon joined by socialite Paris Hilton. Other guests at the party included all-girl rock band THE DONNAS, burlesque queen DITA VON TEESE and '80s pop star TAYLOR DAYNE.
