How Mariah Carey's 'Princess Fairy Tale Is Coming True' with Her Billionaire Fiancé James Packer

Everyone knows Mariah Carey loves a good wedding.

After all, this is the woman who dressed as Cinderella and shut down Disneyland just to celebrate renewing her vows with ex-husband Nick Cannon. Now engaged to her billionaire fiancé James Packer, who proposed on Jan. 21 in New York City with a whopping 35-carat diamond engagement ring, the Grammy-winning superstar might have found her happily ever after.

“Mariah was always a hopeless romantic,” a source close to the singer tells PEOPLE in this week’s issue. “She deserves the dream and I am sure James will give her just that.”

Estimated to be the fourth-richest person in Australia with a net worth of $4.7 billion, Packer, 48, recently signed a lease for a luxury home outside L.A. at a little less than $250,000 per month, where Carey will raise her 4½-year-old twins, Monroe and Moroccan, from her marriage to Cannon.

The singer “always loved being showered with roses and diamonds,” says a pal. “And now her princess fairy tale is coming true.”

While this will be Carey’s third marriage – she previously tied the knot with music executive Tommy Mottola, 67, and America’s Got Talent host Cannon, 35 (their divorce is still pending) – friends say she can’t wait to be Packer’s wife.

“She is super excited,” says an insider. “And she has never been in a better place.”

With plans still to be finalized, friends are anticipating nothing less than the best for Carey’s next wedding.

Adds a pal: “Mariah is someone who likes to be taken care of.”
