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.

Nicole started her birthday off right, in a cabana with her girlfriends soaking in the sun and working on her tan for her party taking place tonight. Friends including actor Hill Harper, Quinton Aaron, best known from “The Blind Side,” and cousin Meleana Brown from the show “Duets” joined her later in the day for dinner at Lavo Restaurant before heading up to a VIP table in the nightclub.

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.

Simon Cowell got Nicole Scherzinger (@NicoleScherzy) cake with his face on it for her BDay!

It should have been the icing on the cake but instead Simon Cowell’s birthday surprise for Nicole Scherzinger took the biscuit.

The sardonic talent show don waited until the last minute of the second day of Seattle auditions to give his fellow judge her treats.

Today she turned 33, and was apparently so keen to celebrate the milestone with her new colleagues that she’s issued constant reminders.

The Pussycat Doll even emailed Simon last night, lest he forget.

She needn’t have worried, as the irascible judge was planning to have his fun with her.

After flowers from L.A Reid and a 500-strong rendition of Happy Birthday from the audience led by Paula Abdul, not to mention plenty of teasing from Simon,  he finally handed over his ‘gifts.’

First up was cake with a picture of him on it and just one candle, he then followed it up with a T-shirt also featuring his visage, with the additional detail ‘I heart’ detail on it.

Nicole smiled broadly as she held up the joke garment, but it seemed she was expecting something more from the billionaire.

So perhaps the state of the cake, which was photographed and uploaded to Simon’s Facebook account, betrayed her real feelings.

The image had been roundly defiled, all in the name of fun, we’re sure.

An insider confirmed that she was disappointed: ‘I think Nicole might have been expecting something fancy.

'Simon’s face on a cake and T Shirt probably wasn’t exactly it, but no doubt she will get her own back when his birthday comes around!'

But Nicole still got quite a fuss, nonetheless.

No less than four groups asked to sing special versions of Happy Birthday in their bids to impress her.

It was an emotional day for the newest member of the panel, who admitted she’s still getting her head around her fantastic new job.

The singer, who was wearing a stunning silver mini-dress and had her hair swept up on her head, said: ‘I am so excited, I woke up this morning and its my birthday,  I have an amazing job working with three of the most wonderful people in the world that I have ever met… ‘

Before joking: ‘Well two actually – and then there’s Simon too!’

She reserved extra praise for Paula Abdul, Scherzinger gushed: ‘She is my idol and she wished me happy birthday today! ‘

'And now I get to sit next to her, and stare at her in a kinda creepy way, I think, and just because I just love her so much'

One insider said: ‘Nicole has been reminding everyone for weeks that her birthday is coming up and she even emailed Simon last night to remind him so he wouldn’t forget when he arrived at work today, she as so cute’

But it was L.A. Reid who welcomed her with a big bunch of flowers, while Simon is keeping his big surprise under wraps.

Today is Scherzinger’s actual birthday but she already started celebrating in earnest at the weekend in Vegas.

The beauty, who is dating F1 champion Lewis Hamilton, enjoyed a daytime event and then partied the night away at TAO Nightclub at the Venetian hotel.

For the evening event she looked stunning in a glittering mini dress which she paired with taupe shoes and bag.

Her long raven hair in soft curls which cascaded over her shoulders.

In the day, Scherzinger was presented with an an amazing five-tiered cake decorated in gold and pink with her name in glittering letters perched on the side.

The cake was covered in musical symbols, a microphone and the second tier even featured a corset

But it probably could’ve benefited from Simon’s face.
