In her other hand she held an empty flute suggesting she'd just popped the cork on the pricey fizz in her backstage dressing room at Caesar's Palace.

The 46-year-old songstress was busting out of her black top that just had some laces stretched across her bosom to hold things place.

Her figure-hugging outfit also showed off her newly trim waist and voluptuous derriere.

In a second video, she tosses ice cubes at the camera  with her sunglasses pushed back on top of her head.  

Her expensive diamond pendant necklace is in full view as it dangles just above her exposed bosom as are her matching large hoop earrings. 

No doubt Mariah had decided to celebrate the fact that her ex Nick Cannon has finally said he will sign their divorce papers after a year of prevaricating. 

That clears the way for her marriage to  Australian multi-millionaire James Packer, to whom she became engaged in January.

In a four-minute rap posted to SoundCloud - and then shared on his social media accounts - the 33-year-old America's Got Talent host opened up about the drama surrounding his divorce.

And he finished it by finally agreeing to officially end his marriage to Mariah, rapping the line: 'F*** it, I'll sign these papers.'

A good portion of the rap focused on Nick's love for his children with his ex - five-year-old twins Monroe and Moroccan.

He rapped: '...What we really need to think about is how a child deals, how a child feels, because we got two.' 

'It's f***ed up that the time that you spend with your own kids is called visitation,' the performer went on. 

Nick and Mariah first separated in August 2014, with Nick filing for divorce in December of that year.
