Former Hills starlet Audrina Patridge rang in her 26th birthday on Saturday by the pool at Wet Republic in Las Vegas. Joined by her brother Mark Patridge and even on-again off-again romantic interest Corey Bohan, the reality star partied in her bikini at the MGM Grand with a round of drinks and good friends. The other day, I reported about how Audrina Patridge was back with her old boyfriend Corey Bohan in their roller coaster romance.

Even though Audrina Patridge was celebrating her birthday at Wet Republic in a sexy bikini with her squeeze, not everything was good between the two of them. TMZ reported that a day before Audrina’s birthday bash, BMX rider Corey was cited for public intoxication in Hermosa Beach, but was released after posting $500 in bail. Audrina Patridge’s show,  the Audrina Show, airs Sunday nights on VH1, if you are interested.
