If she was a diva like Mariah Carey, her helper would be fired!

Paris Hilton arrived at LAX last night to catch a flight to Australia, except her assistant accidentally brought the socialite's already expired passport, so she was forced to miss her plane and catch the next one at midnight. The heiress looked drop dead gorgeous in a pineapple skirt and crop top, but we have a feeling she changes into sweats once she's up in the air. Gotta look good for your adorning public!

The Simple Life star is headed down under for a handful of work commitments. First, she will promote her new fragrance Gold Rush in Melbourne on Thursday and Friday, then she will DJ at Marquee at The Star in Sydney on Saturday before rounding out her trip with a club appearance at Brisbane's Fluffy nightclub on Sunday.

She's probably set to make a bazillion dollars from all this, so good thing she managed to take off!
