Mariah Carey is having "a lot of fun" with James Packer

A source told E! News: "[Mariah]‘s having a lot of fun being courted.

"It’s very different than when Nick Cannon was wooing her. To her, Nick [Cannon] was a boy. James is a man."

Meanwhile, James is reportedly keen on asking Mariah -who has four-year-old twins Monroe and Moroccan with estranged husband Nick Cannon - to marry him as soon as her divorce is finalised.

A source said: "James wants to marry her sooner rather than later, and she is very open to the idea."

However, another insider denied the pair were considering an engagement just yet.

They added: "They are not talking marriage. That's ridiculous. She's enjoying his company, but she's also trying to remain cautious.

"This trip is a chance for her to really get to know him. She hasn't 100 percent let him in yet."

However, whilst Mariah has moved on, her ex Nick admitted he wouldn't rule out the chance of them getting back together.

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."
