Could Gretchen Rossi look any sexier in her barely there bikini?

The Real Housewives of Orange County star stripped down into one of the skimpiest bikinis imaginable over the weekend in Las Vegas, showing off her impossibly perfect body in sexy style – and Breaking Celebrity News has the photos and all the details about her scorching hot weekend in Sin City!

Rocking a custom Marco Marco embellished swimsuit with Steve Madden heels, a Beach Bunny wrap and Royal Asscher ring, the reality star hosted Bling Beach – a competition giving the girl with the most blinged out swimsuit a $5,000 prize – at TAO Beach. 

She was joined by her beau Slade Smiley at TAO Beach’s Grand Cabana, where the duo engaged in a PDA fest most of the day and even fed each other grapes!

Gretchen wasn’t the only Orange County bikini babe over the weekend!  Tamra Barney steamed up Mexico with her fiancé Eddie Judge at the Villa del Palmar Islands of Loreto resort.
