Haute Event: Gretchen Rossi Hosts at Tao Beach, Cheryl Burke, Stacey Keibler and More at Lavo, Tao

Gretchen Rossi of "The Housewives of Beverely Hills" hosts the Bling Beach Bikini contest at Tao Beach with boyfriend Slade Smiley.

Gretchen Christine Rossi of “The Real Housewives of Orange County” hosted Bling Beach at Tao Beach at the Venetian, giving the girl with the most blinged out swimsuit a $5,000 prize. The reality star posed for a few photos on the red carpet, rocking a custom Marco Marco swimsuit, Steve Madden heels, Beach Bunny wrap and Royal Asscher ring.

Rossi’s beau Slade Smiley and friends overlooked the entire pool party as they took over Tao Beach’s Grand Cabana. Fans immediately recognized the star and were eager to snap photos. Rossi took the time to let a few come into the cabana to take a photo with her. Soon enough the line began to wrap around the pool as she graciously posed with each adorer. Rossi and Smiley were affectionate and playful all day.

The twosome danced to the music and jumped into the DJ booth to learn a thing or two from DJ Lema. She even cooled Smiley down and hand-fed him grapes. The Bling Beach competition started and Rossi was happy to judge, helping the crowd decide what blinged out beauty would walk away with the $5,000 prize.

Before hitting the Simon G Summer Carnevale, George Clooney’s girlfriend Stacey Keibler was spotted at Lavo at the Palazzo. She was joined by a friend and enjoyed the atmosphere in the lounge. The two fueled up for the night on espresso martinis and the one-pound Kobe meatball.

“Dancing With the Stars” pro Cheryl Burke also dined at Lavo Restaurant with a small group of friends, fresh from the Simon G Summer Carnevale. The dancing pro enjoyed specialties including the Kobe meatball and caprese salad.

E! News personality Giuliana Rancic, who also attended the Simon G event, was spotted at Tao Asian Bistro at the Venetian with friends enjoying the famed Chilean sea bass and King salmon special.
