The '#Beautiful' hitmaker, who split from Nick Cannon last summer after six years of marriage, and the Australian billionaire have only been dating since last week, but they are reportedly already talking about exchanging vows.

A source close to the 45-year-old singer told gossip website TMZ.com James wants to marry her sooner rather than later, and she is very open to the idea.

The 'Fantasy' hitmaker is still legally married to Nick, with whom she has four-year-old twins Monroe and Moroccan, but their divorce is expected to be finalised in the near future.

The couple, who were introduced by mutual friend Brett Ratner, are currently holidaying with her children on a lavish yacht near Sardinia, where James has been blaring Mariah's music for everyone in the area to hear.

The 47-year-old businessman, who has an estimated fortune of $4.7billion, fell for the singer after attending her concert in Las Vegas in early May and has been pursuing her ever since.

He was previously linked to top model Miranda Kerr, 32, following his split from second ex-wife Erica in 2013.

While Mariah has clearly moved on, Nick recently admitted he would never rule out the idea of them getting back together.

Speaking in April, he said: "It's one of those things, I'm a hopeless romantic too. Through this learning process, you never say never.

"To me one thing I know, that will always be the love of my life, always be my family and that's never going to change."
