Mischa Barton struts on stage for the spring/summer 2009 ready-to-wear fashion show of HUGO on Thursday at the Westhafen industrial area in Berlin, Germany.

The former O.C. star takes the cover of the August edition of Nylon magazine, and speaks of her embarrassment following her arrest for driving drunk in December.

“That was a low point for me. I never, ever would have thought I would be arrested,” Mischa said.

‘I was disappointed because it associated me with a group of girls that I would rather not be associated with. That was the biggest bummer for me – I didn’t leave my house. I was too embarrassed.

In the interview Mischa also confirmed rumors she had turned down a role in Gossip Girl.
