Adrianne Curry celebrated her 29th birthday with perfectly tiny string bikini in Las Vegas

America's Next Top Model winner Adrianne Curry has been having a wild time lately. Kicked out of a Comic Con celebration for showing too much skin, and then making a scene on the Playboy Party red carpet the following night, it was anyone's guess what wild antics she'd get up to for her 29th birthday.

But it seems that for the earlier part of the day at least, Adrianne was content to enjoy a little poolside R&R at Encore Beach Club in Las Vegas.

You'd be forgiven for thinking that the model was at work, as she posed perfectly for the cameras in her tiny string bikini.

Perhaps her relaxed approach had something to do with preemptive celebrations the night before.

Having been out to dinner at Vegas restaurant Society the previous evening, the model continued to live it up until the early hours, tweeting on the morning of her birthday: 'Mercy! Mercy! I got back to the room at f****** sunrise...actually..after it. ugh'

Her mood appeared a little pensive a few hours later as the gravity of the day sunk in: 'dude...I'm 29 now. tis the year long farewell tour to my 20's.'

She certainly had her health in mind during the day, snacking on a healthy fruit salad and juice in the shade during a brief break from the pool.

She kept fans updated as to her condition, confirming suspicions of a hangover as she tweeted later on: 'me and @oneeyedjedi are dying at the pool...dying..ffffffffuuuuuuuuuu! Vegas...destroyer of souls.'

She nevertheless looked fresh as a daisy as she splashed about, showing off perfect pins and a flat stomach, though admittedly her large dark sunglasses concealed much of her face.

And that short respite was apparently all she needed to recharge for yet another full-on night.

The model continued her self-named 'f*** it all tour' that night at Surrender nightclub, also located at the Encore Club.

Adrianne can hardly be blamed for wanting to cut loose.

This is her first landmark celebration since splitting with Brady Bunch star Christopher Knight in May.

The couple had been together for five years, starring together in reality show My Fair Brady. They announced their split on their fifth wedding anniversary.

The pair insisted that the decision was mutual, citing irreconcilable differences.

Their manager Phil Viardo made the announcement via website Hollyscoop.com.

He told the website: 'After starting a relationship with what seemed to be irreconcilable differences, the couple has reached a period where those differences are no longer appreciated.'
