Mischa Barton has reportedly become a bit of a DUI diva since being arrested for drinking-driving last week.

The former OC star was booked to open the CatHouse Loungerie club at the Luxor Hotel in Las Vegas on Saturday night but after her arrest made headlines around the world, her handlers reportedly started upping her demands.

A source told Vegas Confidential: “[the handlers were] difficult … They wanted a bigger jet [sent over for her]. Mischa wanted to bring her dogs.”

Mischa’s people also started complaining about the invitation used to promote the event, which featured a scantily clad woman: “[Her reps] wanted the invitation redone because they thought it was too risque for her image.”

And they also asked for Las Vegas vixons Paris Hilton and Nicky Hilton to be barred from attending: “They were blacklisted. Mischa’s team didn’t want her to be associated with the party-girl scene [right now].”

According to the source, the CatHouse’s owners quickly grew weary of her demands and cancelled her appearance - which would have earned her $30,000.
