Mariah Carey made her debut as a DJ on Saturday night at the 1 OAK nightclub inside the Mirage Hotel and Casino in Las Vegas, where she put her b**ty and cleavage on full display.

The 46-year-old singer wore a tight black corset that highlighted her ample cleavage, a pair of thigh-high fishnet stockings with suspenders, a leather jacket and strappy Christian Louboutin stilettos.

She completed her look with a diamond necklace and hoop earrings, and left her blonde tresses down for a more sexy vibe.

The diva arrived fashionably late to the party around 1:17 a.m. An eyewitness reported to ET that Carey headed straight to the DJ booth, where she was joined by her pal, DJ Suss One.

“I got a good friend of mine with me tonight,” he told the crowd before pressing play on “Fantasy”, one of Carey’s classic hit songs.

“Where my Mariah Carey fans at? Mariah’s gonna step in, and we gonna make a movie.”

Carey appeared to be in good spirits all night, dancing, sipping on cocktails, and talking to fans on the microphone.

Once she was settled in, she kicked off her set by playing Fat Joe’s “All the Way Up.”

Along with her own hits, Carey also played popular tracks from the ’80s and ’90s, including Lil’ Troy’s “Wanna Be a Baller” and Luniz’s “I Got 5 On It.”

The party guests later took to Instagram to share highlights from Carey’s appearance and DJ set.

Club owner Eli Pacino captioned a video of the diva playfully posing and smiling for photographers on the red carpet, “@1oaklv welcomes @mariahcarey!!!!!”

DJ Suss One also shared some pictures and documented the night on his Snapchat account, with many of the videos featuring Carey.

In one of his captions, he called Carey “family”.

Before Carey played DJ, she performed a show at Caesars Palace as part of her #1 to Infinity residency.

Blac Chyna was in attendance, sporting pink-colored locks and a tan halter dress. At one point, Carey even brought the 28-year-old pregnant model on stage, where she received a lap dance from one of the male dancers.

“It was truly a honor to grace the stage with Mariah tonight,” Chyna later wrote on Instagram. “The show was amazing & she was gorgeous!”

Rob Kardashian’s fiancée also shared pictures and videos from the concert via Snapchat, including plenty of her singing along to Carey’s songs.

“She’s so legend,” Chyna wrote over a video of Carey belting out “Hero.”

This appearance in Las Vegas follows Carey’s recent appearance in Sin City, where she was spotted hanging out with Chrissy Teigen and John Legend.

It’s clear that Carey is not shy when it comes to showing off her assets, and she certainly turned heads at her first DJ gig in Vegas.
