Superstar Mariah, who is married to presenter and rapper Nick Cannon, made her way to the awards ceremony in Monte Carlo, Monaco, on Tuesday night (27 May).
Mariah opened the show with a performance and dazzled in a plunging black gown with sheer panels, before slipping into a more risqué dress with beaded embellishments.
No doubt the 'Hero' hitmaker was over the moon to have won the 'Pop Icon' award and the coveted award for the 'Best Selling Solo Artist of All Time'!
Sharing a backstage of photo Monroe and Moroccan, Mariah said in a sweet messsage: "The best awards I've ever received: Roc & Roe!! Thank you Melissa & all at the World Music Awards in Monte Carlo."
It was a special day for the 44-year-old, who was celebrating the release of her 14th studio album, Me. I Am Mariah... The Elusive Chanteuse.
The deluxe edition of Me. I Am Mariah... The Elusive Chanteuse features collaborations from the likes of Mary J. Blige and R. Kelly.
Speaking of Mariah's album, husband Nick was full of praise for his wife in a message posted to Instagram yesterday.
He said: "If you ain't got this album yet you ain't living right!! Masterpiece!! Blessed to have a front row seat to watch & witness a true genius create and share her art with the world."
