Mariah Carey’s grandiose Las Vegas residency got off to an auspicious start on Wednesday evening in front of a full house at the 4,100 capacity Colosseum at Caesars Palace.

The 45-year-old singer put on a bravura display after confidently squeezing her voluptuous curves into a plunging bodysuit that left very little to the imagination.

Teaming the sequin embellished leotard with fishnet tights and strappy gold heels, Mariah belted out the hits while showing off her cleavage.

But naughty soon turned to nautical for the singer, who indulged in a frisky display with a hunky dancer dressed in sailor stripes and sea-faring cap.

Grabbing Mariah around the waist, the male backing dancer hoisted her up as fans at the Vegas venue cheered appreciatively.

 

The estranged wife of Nick Cannon performed her 18 number one hits in chronological order donning several costume gowns and even bringing out expensive props such as a neon yellow jet ski and hot pink Thunderbird convertible on stage.

The wardrobe for her show had one main staple: a plunging neckline – but there was a potential catastrophe with one particular design that prompted her wardrobe to appear onstage and furiously mend the back of her tight fitting dress while she powered through another track.

Specifically for her performance of the 2005 hit We Belong Together, the mother-of-two slipped into a custom Azzedine Alaïa ruffled frock that was complete with an elaborate Elizabethan collar.

And during the 1997 single Honey she showed off some major leg in a black long sleeve one-piece on the back of a fluorescent jet ski.

In true Mariah fashion, every set detail was adorned with her signature butterfly symbol in the most grandiose way possible.

On January 15, Mariah announced her Vegas residency on The Ellen DeGeneres Show.

 

‘I have to hope that the fans will enjoy this cause I’m gonna be performing, which was kind of inspired by my album #1’s, and this is now the updated version with 18 of them,’ she said during the appearance.

Following in the footsteps of Britney Spears, Shania Twain and Reba McEntire, the hitmaker very temporarily filled in for famed Caesars headliner Celine Dion, who later announced she is reprising her residency show after taking care of her ailing husband.

Not sold out yet: Tickets for her next shows – May 9 and 10 – are still available at the box office and online

To Mariah’s disappointment, fans did not exactly rush to buy tickets when they went on sale in late January.

Poor ticket sales have left several of her upcoming concerts with empty seats and Mariah’s shows are falling behind early sales projections.

Tickets for her next shows – May 9 and 10 – are still available at the box office and online.
