Hollywood socialite sisters Paris and Nicky Hilton returned to Las Vegas for another three days of nonstop, around-the-clock party fun -- their third visit in less than five weeks -- and the siblings led an all-star invasion at our Strip restaurants and nightclubs. Their first stop upon arrival was with makeup princess Rain Andreani, and then they were off for dinner at Eva Longoria Parker’s Beso restaurant and Eve the Nightclub in Crystals at MGM’s CityCenter.

Paris started off the evening with a shot of Don Julio 1942 tequila chilled with pineapple juice. The sassy sisters shared Eva’s guacamole and tortilla soup, and for the main course, the newly trimmed-down Paris ordered the Beso burger but swapped the fries for a salad.

Then it was a three-in-a-row assault on the nightclub scene. From Eve, they hit Victor Drai’s XS in Steve Wynn’s Encore and then Tao in The Venetian, where they stayed as dawn broke. Paris was glammed up in a gold cocktail dress, while Nicky kept it casual with a striped shirt and leggings. Nicky’s boyfriend David Katzenberg joined the girls when they arrived at Tao.

Hair guru to the stars Michael Boychuck put his glam squad into action again before Paris set out for the Floyd Mayweather Jr.-Shane Mosley fight. His beauty team from Amp at the Palms and Color at Caesars Palace along with a Rain makeup expert turned the girls into million-dollar princesses for their arrival at MGM Grand Garden Arena. It was a lucky night for Paris because she bet big on Floyd to win on points and go the full 12 rounds, and it paid off with a huge win for her. So big she even used Twitter to report the coup!

Paris and Nicky then returned to Tao again and led the contingent of celebrities there that we reported this morning right here at Vegas DeLuxe. They had so much fun that they decided to stay another night and hit Tao’s sister hotspot Lavo in the adjoining Palazzo.

Paris tweeted: “Just had dinner at Lavo. The food is so good there! :)” Nicky added her own tweet: “Lavo is one of our favorite restaurants in Vegas.” After dinner, Paris headed upstairs to the boutique nightclub, where she immediately jumped into the spotlight and danced on the banquette throughout the night, staying until the club closed at dawn this morning.

The heiress was decked out in diamonds and even had on sparkly stilettos. DJ Vice wooed her into his booth, where she sang one of her songs and then gave shot-outs to Lavo and Tao owners Noah Tepperberg and Jason Strauss.

The Hiltons are probably headed back to L.A. today, but they’ll be back faster than we know it. You just can’t keep those who love life from enjoying it to the fullest here in Las Vegas. “I just love Las Vegas,” Paris said.
