THE OC star Mischa Barton was left wet and angry at a recent Hollywood party when the wooden boards over a swimming pool collapsed.

The actress was partying with pals on 5 February (06) at the undisclosed location when a makeshift dancefloor over a pool gave way plunging Barton and other revellers into the water below.

According to American magazine In Touch, The 20-year-old beauty wasn't hurt, but she got soaked, ruined a Chanel jacket and destroyed her Sidekick (mobile phone).
