Audrina Patridge Has a Bikini Birthday Bash in Vegas (PHOTOS)

Best Bikinis of 2011
The hottest beach bods so far this year!
It’s Audrina Patridge’s party and she’ll bikini if she wants to!

The reality star was spotted flaunting her fabulous bikini bod at a belated 26th birthday celebration at Wet Republic on Saturday, May 14. The former Hills star showed off her, er, hills in a skimpy floral Tigerlily Ines Bikini. Audrina rang in her 26th birthday on Monday, May 9, but decided to have a belated b-day bash at the famous Las Vegas pool party.

Although Audrina was having a fun time showing off her bikini bod, her on-again, off-again boyfriend Corey Bohan didn’t have such a good weekend.

TMZ reports that the BMX rider was arrested in Hermosa Beach, California for misdemeanor public intoxication on Friday, May 13. Cory and Audrina had a very public breakup over Twitter in March but TMZ hints that the two are reportedly back together.
