Stella McCartney London Fashion Week Celebrity Pictures: Kate Moss, Alexa Chung, Rihanna, Shailene Woodley

London Fashion Week kicked off on Saturday with a magical presentation from Stella McCartney. Many of Stella's friends came out to see her Autumn/Winter 2012 London Evening Collection, which began with a vegetarian dinner for the likes of Kate Moss, Jamie Hince, and photographer Mario Testino. Models were seated at the tables with guests, and following the meal, excused themselves to perform a choreographed dance routine in Stella's designs. The fun didn't stop there for one guest. Alexa Chung was called to the stage by a magician who hypnotised her and then levitated her body above swords! Stella herself got in on the games by performing a card trick.

Rihanna seemed to be enjoying herself at the party as well. After posing for photos on the red carpet in a sexy jewel-toned gown, she met up inside with Kayne West. Rihanna turns 24 today, and started her celebrating last week at a private post-Grammy party in LA. Another young star, Shailene Woodley, mingled with Vogue editor Anna Wintour, fashion icon Twiggy and actress Minnie Driver. Shailene doesn't have an Oscar dress yet, but said at the bash, "I have no idea what to wear, so yes, I’m always looking for red carpet dresses."
