Friday night the solo artist and lead singer of the Pussycat Dolls dined at LAVO, enjoying signature dishes before heading up to the nightclub where she was surprised with birthday cupcakes. Scherzinger danced on the banquette with glow sticks and a blinking ring, and being extremely gracious, she invited several club goers to join her for drinks.

The party continued Saturday afternoon as she returned to Marquee Dayclub, commanding a cabana and taking in the sounds of DJs Roger Sanchez and Dirty South with a surprise set by ATB. She was treated to a cake designed by Gimme Some Sugar before hopping into the DJ booth with Roger Sanchez, jumping, dancing and whipping her hair as fans cheered.

The celebrating wrapped up Saturday night at TAO. After walking the red carpet in a Jean Feres Couture dress, Scherzinger took time to greet 50 fans in the nightclub’s Opium room before sitting down to dinner under the watchful eye of TAO’s famed Buddha. She made a special request for TAO’s popular Sea Bass dish, and made a game out of the restaurant’s Giant Fortune Cookie dessert, doling out the fortunes to each of her friends and having them read them aloud.

Upon arriving in the nightclub she grabbed light sticks which she waved around as she danced in her skybox overlooking the club as her friends from high school joined the party. As a five tier cake with a microphone was presented to the pop star her friends, including members of the Lion King cast and the A Cappella group Mosaic, sang happy birthday. As the song came to an end, Nicole grabbed the mic, shouting out, “What’s up Vegas?”.

DJ Vice promptly began to play her new single “Right There” featuring 50 Cent and she surprised the entire club with an impromptu performance.
