On the eve of London Fashion Week, the cosmetics brand threw the bash at Battersea Power Station to celebrate its working relationship with the fashion icon.
Arriving at the disused power station via helicopter, Moss was welcomed on stage by The Noisettes, who also performed for guests.
Fellow Rimmel London ambassador Georgia May Jagger joined the celebrations, along with Harry Potter star Bonnie Wright and her fiancé Jamie Campbell Bower. The Vaccines, who appear in a new advert for the brand, were also present.
Solange Knowles, Sadie Frost, Meg Matthews, Rachel Stevens, Cher Lloyd, The Only Way Is Essex's Gemma Collins and Dionne Bromfield were among the other guests at the party.
A new Rimmel London lipstick collection designed by Moss goes on sale nationwide from September 28.
