Unsurprisingly, the pre-New Year’s Eve party Mischa Barton was supposed to host this weekend in Las Vegas before she got arrested for drunk driving, was cancelled.

The young actress would have received quite a hefty paycheck if she were to appear at the event - the opening of CatHouse at the Luxor, but according to reports Barton pulled out and won’t be showing her face anywhere near Las Vegas.

On Thursday afternoon, a publicist for the lounge confirmed that she was still set to attend the party, despite her trouble.

"We are aware of Mischa Barton's incident last night, but at present she is still expected to host the CatHouse Grand Opening at the Luxor on December 29th," the spokesperson said adding "We will let you know if anything changes."

The 21-year-old starlet, best known for her role as Marissa Copper on the hit Fox television drama "The O.C." was arrested and briefly jailed on Thursday on suspicion of DUI after she was pulled over in West Hollywood. According to police, her vehicle was straddling two lanes of traffic and she failed to signal a turn.

"During Ms. Barton's detention, it was determined that she was an unlicensed driver and was driving while under the influence of an alcoholic beverage," the official report said. According to Reuters, Barton was also suspected to be in possession of marijuana and an unidentified controlled substance.

The actress was freed on a $10,000 bail after spending around seven hours in the West Hollywood jail, and was picked up by her mother in the family's black Mercedes. An unusually disheveled Barton covered her face with a scarf to hide from photographers as she rushed to the car; once inside, she slid down in the back seat.

She is due in court on February 28.
