He's got her feeling emotions! Mariah Carey gushes about dating James Packer

We'll have to call this "the James Packer glow".

Mariah Carey was grinning from ear to ear as Entertainment Tonight asked her about dating the Aussie billionaire.

The 45-year-old diva didn't say too much at the Harper's Bazaar ICONS party in New York, but what she said was telling. Watch above.

Mariah and James, 48, were first seen together on holiday in the Mediterranean in June, with their relationship evolving after years of friendship.

The singer first acknowledged their romance when she dedicated 'Hero' to him at one of her Las Vegas shows in July. See it below:

In August, the mother-of-two told Extra that James is "a very generous man".

Later that month, Mariah's rep denied a New Idea report that she was pregnant with their first child together, saying "it's false reporting, nothing more".

Back to the yacht then for these two...
