Nicole Scherzinger (@NicoleScherzy) premiered her newest single One More Shot at Tao

It’s been a weekend-long early 34th birthday celebration for former Pussycat Dolls lead singer Nicole Scherzinger, and other celebrities joined in her celebration, including Chris Paul of the L.A. Clippers, who sprayed the “X Factor: U.K.” judge with water instead of champagne.

Fresh from a Friday at Tao Beach and dinner at Lavo in the Palazzo with friends and family, including actors Hill Harper and Quinton Aaron and cousin Meleana Brown (“Duets”), Nicole continued her celebration Saturday at Tao Beach in the adjoining Venetian. The “Dancing With the Stars” Season 10 champion with Derek Hough donned an animal print Vix bikini and cover up with gold Giuseppe Zanotti heels. (In “Men in Black 3,” she portrays a dominatrix in black leather and high heels.)

Nicole, who turns 34 on Friday, and her party posse overlooked the pool scene in their grand cabana. A parade of blow-up, pool-party animals made its way through the daytime revelers to the birthday girl, with two shirtless studs — guy candy for the ladies! — leading the way with a surprise from Herbal Essence: a four-tier red velvet cake adorned with tropical accents and cherry blossoms.

Nicole, an Herbal Essence ambassador, also received a gift from the hair-care company: an Alexander McQueen baby pink leather clutch with quilted detail and gold accents. Nicole got on the mic and said. “Thank you for coming out to celebrate my birthday with me! This is my dedication to you.” Just as she finished her words, Jay-Z and Kanye West’s “N***** in Paris” played, and the guys and girls went wild.

Throughout the afternoon, Nicole sported dangling mustache glasses, posed for photographs with fans and later jumped on the mic once again to perform a medley of her hits, including “Don’t Cha.” She danced to the sounds of DJ Lema, who dropped the world premiere of her newest single “One More Shot.”

The birthday celebration continued with dinner at Tao, followed by the upstairs nightclub. Nicole wore a gold and glittery Haute Hippie dress, Norman Silverman bangles and ring, a Loree Rodkin ring and gold Giuseppe Zanotti heels. Joined at an elevated VIP table with friends including Quinton, Nicole later jumped in the DJ booth with resident DJ Vice as he led the nightclub in “Happy Birthday.”

After another cake presentation, she said, “What’s up, Vegas?! Thank you so much for coming to celebrate my birthday. Let’s give it up for my boy DJ Vice!” Also at Tao (the beach, restaurant and nightclub): Francia Raisa (“The Secret Life of the American Teenager”), “American Idol” Season 5 champion Taylor Hicks (who starts a residency at Bally’s on Tuesday), “Idol” Season 5 alumnus Elliot Yamin and “The Hangover” heartthrob Justin Bartha.

In the midst of dancing with her girls, Scherzinger decided to jump on the mic, giving the crowd a surprise performance of all of her hits. Her birthday weekend will resume today at Tao Beach and will last late into the night as she continues the celebration at Tao Nightclub.

Nicole Scherzinger (@NicoleScherzy) at Chateau Nightclub & Gardens in Vegas - recap

Nicole and Nelly inaugurated Labor Day Weekend in Las Vegas last night at Chateau Nightclub & Gardens (www.chateaunightclublv.com) at Paris Las Vegas with an explosive performance.

The Hawaiian-born beauty surprised Nelly as he sang “Dilemma,” when she joined him in the DJ booth and flawlessly sang the female vocals in the song, originally performed by Kelly Rowland. Wearing a sexy cherry red dress and nude Christian Louboutin shoes, Scherzinger matched her signature Sugar Factory (www.sugarfactory.com) Couture Pop perfectly as she sang along with her friend. With Nelly’s encouragement, Scherzinger then sang an acapella version of her hit Pussycat Doll single, “Don’t Cha,” with the ladies in the club excitedly singing along.

Much to the delight of the amped crowd, Nelly performed several of his hit songs including “Air Force Ones,” “Just a Dream,” “Hot in Herre” and “Ride Wit Me.” He jumped atop the ledge of the DJ booth, Moet Rose Champagne in hand, and gave many “shout outs” to the club; from “the beautiful shorty who’s about to get married” to “all the fellas in the room,” as well as a nod to his “beautiful co-host, Nicole Scherzinger.”

Scherzinger commented that she and Nelly were friends, and that the two have even spent some time in the studio together. Prior to their performances, Nelly and Scherzinger partied in connecting booths with their friends. Scherzinger danced on the booth and waved to excited fans, as Nelly smiled and showed off some dance moves when the DJ played some “old school,” including a mix of Snoop Dogg and Dr. Dre. At a nearby table in the VIP area, Flo Rida and his friends partied alongside Nelly and Scherzinger, with bottles of Moet Rose Champagne and Ciroc Vodka with mixers. Also in the VIP area were Hill Harper from CSI New York, seven-time Pro Bowl NFL veteran, Orlando Pace, Freddie Mitchell, formerly of the Philadelphia Eagles, James Harden from the Oklahoma City Thunder and J.J. Hardy from the Baltimore Orioles. Mitchell was recently featured on Millionaire Matchmaker.
