The 47-year-old showed off her curves wearing a revealing glitter leotard and fishnet tights as she strutted her stuff on stage, The Sun reports.
It comes after she received very negative reviews earlier this week when she was accused of being somewhat lacklustre:
It was however a very different story for her final night and Mariah showed exactly why she is the biggest pop diva in the world.
Joined by a cohort of sexy backup dancers, the mum-of-two energetically performed her catalogue of hits.
She was joined by her on/off boyfriend Bryan Tanaka who looked very dapper in a smart suit before showing off his moves on stage.
Mariah’s residency at the Colosseum at Caesers Palace started two years ago.
But fans who might have missed her this time still have a chance to see the lady in action — as she announced she would be returning for a series of Christmas shows.
The songstress made the very exciting announcement last night revealing she was will be treating fans to the tunes from her best-selling Christmas album All I Want For Christmas Is You.
Mariah will also be hitting the road very soon — with Lionel Richie.
The music legends have teamed up for a 22 date North America tour titled All The Hits.
