They've been dating for less than a year, but it seems that Mariah Carey has fallen hook, line and sinker for her new fella - so much so, that the pair have gotten engaged.

The singer split from comedian Nick Cannon - the father of her almost-five-year-old twins Morroccan and Monroe - in August 2014, and has been dating James Packer, an Australian billionaire, for less than a year. They first met at a film premiere and became 'friends' in 2014.

Packer reportedly got down on one knee at a restaurant in New York yesterday and presented Carey with a whopper of a '35 carat diamond ring', according to E! News.

They quote an 'insider' as saying: "they fell head over heels in love with one another. It's crazy how perfect they are together, they both know it and couldn't be happier."

It'll be the third marriage for both Carey and Packer. Third time lucky, as they say.
