Mariah Carey can't be humble, even when she tries really, really hard.

Mariah Carey, 45, and James Packer, 48, are planning a “humble” wedding.

Carey, the “elusive chanteuse”, and Packer, the “obscenely wealthy casino owner” recently became engaged after eight months together in which they did more travel than I did on my gap year.

In a recent interview with E! News, Carey talked about their plans, which are apparently going to be low-key.

“It’s so heavy I can’t lift my arm up!” Carey said about her 35-carat diamond enagement ring which cost an estimated $10 million.

“Oh, dahhhling, it’s aaaaagony.”

“But,” she added, “we are not doing a big wedding because he did two big weddings, and it’s kind of like, ‘I’ve done a big wedding [too]’… We would rather make it beautiful but humble.”

I wonder what humble looks like to Packer and Carey?

Cristal instead of Dom Perignon? Elephants instead of the world’s last black rhino? The Rolling Stones instead of the original Beatles line-up featuring hologram John Lennon and George Harrison?

Carey and Packer were engaged in New York, and Packer, that big lug, is a bit of a softie at heart. It was, she said, “very romantic. He’s an exceptional person and really… it gets more romantic by the day, so it’s very sweet.”

The reason Carey and Packer work so well together is mostly because they’re just super-generous, awesome, modest, humble people, Carey said.

He’s “the guy people go to even if they are barely friends with him, and they look to him to get them through any situation. He’s one of those people that just always is there for people, and I think that is a quality that I haven’t seen — except in myself.”

Carey also said she hasn’t explained to her four-year-old twins Monroe and Moroccan that the enormous Australian they’ve been seeing so much of recently is going to be their stepfather.

“I haven’t talked to them about it completely because they are so young so they don’t really understand things yet,” she said.

“So you have to go slowly and explain things and always make sure they know that this is only going to be good for them. Their lives are not going to change.”

Yeah, don’t worry ‘Roc and ‘Roe, your lives will still be a whirlwind of private jets and preschool classes overlooking the Mediterranean from a yacht.
