Mischa Pulls Out of Hosting Gig

Actress Mischa Barton has pulled out of her hosting gig in Las Vegas, this comes days after Mischa was arrested for a DUI.

Barton was supposed to host the opening of Cathouse at the Luxor hotel on Saturday night. A source told Page Six, "Mischa can't give interviews on the red carpet or deal with the press right now, so they told her she can't do the event."

What a crappy way to end your year--a DUI. Since the New Year is right around the corner, make sure you have a designated driver in advance...or take a cab. That $20 cab fair can save you a big headache...and maybe a life so don't drink and drive people!
