Audrina Patridge In Her Birthday Suit!

Well, almost her birthday suit.

Audrina Patridge was partying it up for her 27th birthday at WET REPUBLIC at MGM Grand.

WET REPUBLIC is a "daylife" (a play on 'nightlife' we assume) party destination. It's a pool and bar and star studded hang out spot.

Audrina was strutting around her ridiculous bod in a teeny bikini.

She's looking CRAZZZY fit!

Looks like she was having fun too! Splashing around, eating her amazing looking cake and just lounging, having a great time.

Love those sunglasses, btw.

Happy birthday, gurl!
