A Skinny Mischa Barton, Ryan Kwanten, Clemence Poésy & More Hit Up G-Star Opening [PHOTOS]

There was definitely a hipster vibe going on last night at the G-Star Rodeo Drive Store Opening last night (December 6) in Beverly Hills, California. Hello Ryan Kwanten!

From a skinny looking and heavily made up Mischa Barton to The Soup’s Joel McHale (why did E! move it to Wednesdays?) to Boardwalk Empire’s Jack Houston, the pretty and hip were representing.

The gorgeous French actress Clemence Poésy is being featured in G-Star’s spring ad campaign and she was a prominent fixture at last night’s event.

G-Star introduced Poésy as its new female face at the opening of its new store on Rodeo Drive last night. Poésy gained worldwide recognition for her role as the coquettish sorceress Fleur Delacour in the Harry Potter movie franchise.

Her acting experience came in handy for the G-Star ads. “I look at fashion shoots like making very short movies and telling a very short story,” she said.
