Mariah Carey, the award-winning singer and songwriter, was spotted having a wild night out in Las Vegas over the weekend.

After performing at The Colosseum at Caesars Palace, Carey headed to club 10ak, where she put on a quite a different show.

Carey, who is currently performing her Infinity residency show in Vegas, is known for her glamorous performance gowns, but this time she went for a sexier look.

She wore a lace sheer corset, sequin embellished Brazilian cut panties, fishnet stay-up stockings with suspenders, a leather jacket, and Christian Louboutin heels.

The star was in high spirits as she joined DJ Suss One at the club, leaving the music to him and instead dancing, laughing, and jumping on the microphone to lead the crowd in toasts.

Carey threw one arm around the DJ’s neck and held what appeared to be a vodka in the other hand, while tossing her hair around.

Her golden locks became the ultimate dance accessory, with her waves flying around her face as she bopped along to the music and spun and twirled around.

The diva was clearly having a great time, and according to insiders, she partied until almost 3am.

She switched between champagne and vodka as she toasted her fans and sang along to some of her favorite tracks.

Carey’s Infinity residency show is currently Vegas’ number one, and she will continue to perform to a packed-out crowd until September 2016.

Earlier in the evening, Carey had surprised the crowd at her Infinity show by bringing Blac Chyna on stage to get a lap dance from one of the singer’s hunky male dancers.

After the show, she held a meet and greet with fans where she was joined by her husband-to-be, Australian billionaire James Packer.

However, Packer decided not to join Carey at the club and missed out on the wild night.

Mariah Carey has many reasons to celebrate and enjoy herself with her recent engagement to James Packer and her successful residency show in Vegas.

The star has been kicking goals in her personal life and in her musical career, and she is not letting her gruelling performance schedule stop her from having a good time in Sin City.

As they say, what happens in Vegas, doesn’t always stay in Vegas.
