The stars came out last night to celebrate the opening of The House of Viktor & Rolf, a new exhibition at the Barbican Art Gallery. Celebs including Mischa Barton (pictured above), Erin O'Connor, Mika, Alexa Chung, Kelly Osbourne, Gareth Pugh, Matthew Williamson and Twiggy, all turned out to support the Dutch designers' special retrospective. Surely last night's celeb-fest, a doll house, and limited edition fragrance bottles are enough to convince you to go see it for yourself.
