Turning 27 never looked so good! Bikini clad Audrina Patridge continues birthday celebrations with a poolside PDA in Vegas

She travelled first to Mexico and then to Las Vegas to ring in her 27th birthday so it is safe to say Audrina Patridge is making sure the celebrations span as many days as possible.
The Hills star today attended a pool party thrown in her honour at the MGM Grand Hotel.
The reality TV favourite posed on the red carpet in a pretty patterned sundress and tan wedges before making her way inside the Wet Republic venue where her party was taking place.

Once inside, the brunette beauty stripped down to a mismatched bikini, pairing a black top with white bottoms, to make a splash in the pool.
Despite the large number of guests, Audrina only had eyes for one person at the pool party - her boyfriend Corey Bohan.
The couple have an on/off relationship but things were definitely on as the pair engaged in an amorous display, cuddling up as they soaked up the sun.

Audrina threw her arms around her beau's neck while dipping her toes in the water as he splashed around in the pool.
The star then slipped into the pool where she sipped on a cocktail and tucked into a bite of the three-tiered pink, black and purple cake she was presented with.
While Audrina was showing her affection for her man in a very literal sense, the reality star also gave a nod to her boyfriend by donning a pair of heart-shaped sunglasses.

The fitness fanatic wasn't shy of showing off her incredible toned figure, with a noticeable tan from her sun-filled break, as she cavorted poolside with her pals.
Audrina recently told Shape magazine how she manages to maintain her muscular body.
She said: ‘LA is so competitive that you want to look your best, though, so I work hard at it. I exercise and eat healthily.'

Earlier in the week the star, who celebrated her birthday on Wednesday, took a trip to Cabo San Lucas where she enjoyed a romantic day at the beach with her beau.
And while she seemed to have a fantastic time on the Mexican getaway, Audrina was just as excited about having another birthday celebration in the party capital of Vegas.
She posted on Twitter yesterday: 'Vegas bound! Who's coming to party with me @WetRepublic tomorrow?!'
