PARIS Hilton was certainly the center of attention at her 33rd birthday bash at Greystone Manor nightclub in LA on Saturday night.

The Hotel heiress decided to dress as a princess for the evening, no surprise there, in a floor-length silk fuschia pink dress, that featured cut-out patchwork around her cleavage area.

The flamboyant design had two thigh-high splits, which did Paris no favours as she suffered an embarrassing fashion faux-pas upon her entrance to her plush shindig.

Paris treated the red carpet to an eyeful of her knickers as she suffered an underwear-flashing wardrobe malfunction.

But judging by these snaps, it could be said the Simple Life reality star was feeling racy for her b-day and didn't wear anything to cover her crotch area.

Moving on swiftly.

In true regal fashion Paris accessorised her outfit with a tiara on her head, and wore a slick of barbie pink lip gloss on her pout.

She centre-parted her hair and kept her luscious blonde locks loose in a cascade of glamorous waves.

Despite her style fail Paris seemed to have had a ball at her birthday party and took to her Twitter page to brag about it:

"YES! #Killedit tonight with my set at @Greystone_Manor! Never seen LA rage so hard at an LA club! So happy you all loved my set so much!"

Happy Belated birthday Paris!
