Model Kate Moss partied like a ROCKSTAR for her 33rd birthday bash in London — Cristal champagne galore! The fashionista rocked the Dorchester hotel with Actress Sadie Frost and Top-shop owner Sir Philip Green amongst others. Moss was having such a good time that apparently her friends had to sing Happy Birthday to her in the LATRINES as she bent over recovering from the nights festivities. Her love slave, rocker Pete Doherty, was sent home after he proclaimed he was a little too tipsy to stay at the fiesta. Happy Birthday Kate!
