Kate Moss at Rimmel London Party Pictures

Kate Moss arrived by helicopter for a Rimmel party at Battersea Power station in London today. She's celebrating 10 years of partnering with the brand, and she kicked off the festivities at a photo call at Claridge's this morning. In honor of the milestone, Kate launched a lipstick line called Kate Moss Lasting Finish Lipstick in collaboration with the label. It's already been a busy week for Kate, who partied with pals at Stella McCartney's 40th birthday bash on Tuesday, and there's sure to be even more fun in store since London Fashion Week gets started tomorrow.
