The X Factor judge enjoyed a daytime event and then partied the night away at TAO Nightclub at the Venetian hotel.
Nicole, who turns 33 next week, looked stunning in a glittering mini dress which she paired with taupe shoes and bag.
She had her long raven hair in soft curls which cascaded over her shoulders.
The former Pussycat Doll 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.

The celebrations comes ahead of her actual birthday which is on June 29.
Earlier in the day, Nicole was presented with yet another cake as she frolicked by the pool at Marquee Dayclub.
She looked very Vegas summer casual in a strapless leopard print beach cover dress.
Her second cake was a five tiered purple and white design with the host venue emblazoned all over it.

Nicole wasted no time in getting into the sweet treat and took a big bite out of the top layer.
She partied to the sounds of DJ Roger Sanchez who was spinning on the decks for the occasion.
The singer has been flitting around the country performing her duties as a judge on the U.S. X Factor after the ousting of Cheryl Cole saw her go from host to being part of the panel.
She has recently gushed about her close relationship with fellow judges Simon Cowell and Paula Abdul.

Nicole said: 'I'm not there to get in between them - I get a front row ticket to the Paula and Simon show every week.'
'I'm fascinated watching them because they've been together for over 10 years,' she added.
'It's such an honour for me to be part of the panel as an artist in today's music industry,' the star said.
Not pictured at the bash was her boyfriend and Formula One driving ace Lewis Hamilton.
The pair were last pictured at premiere for Disney's Car 2 in Hollywood last week.

Nicole has hit back at her former manager Jeff Haddad who told British tabloid Now magazine that X Factor bosses had secretly plotted to have her as a judge all along.
But Nicole told Houston-based syndicated radio show Kidd Kraddick in the Morning that it is not true.

'That's such gossip, man. I was very hurt by that because it was my ex-manager who said that. It just unfortunately goes to show how much he doesn't know, because the people at Fremantle and all the powers that be have no idea who he is because wasn't involved. It was a hard process for me and I'm sure for Cheryl.'
'I started out as a co-host, and I loved the job. I got to meet families and all the contestants and a lot of spend time with them.
