Sydney (AFP) - US pop star Mariah Carey and Australian casino tycoon James Packer are engaged to be married, according to friends who said Friday they were over the moon for the lovebirds.
The couple has been dating for several months and celebrated New Year's Eve at billionaire Packer's Crown Casino in Melbourne, where the singer took to the stage to perform before an intimate audience that included Packer's mother.
"I'm so excited to be in Melbourne with James for New Year's Eve," the husky-voiced songstress reportedly said at the fete.
A close friend of the couple confirmed the upcoming nuptials to AFP and saying she was "over the moon that James has found such happiness with Mariah".
The Sydney Morning Herald reported that Packer proposed to his girlfriend in New York on Thursday.

"Mariah has made James a very happy man, she is a very special person and the family wholeheartedly approves," it added.
