Mariah Carey is living a “Sweet Sweet Fantasy.”

In addition to her engagement to beau James Packer, the

powerhouse singer just wrapped the latest leg of her smash Las Vegas residency

and will next embark upon her first European tour in 13 years next month.

In an exclusive interview with Access Hollywood

correspondent Scott Evans, a glowing Mariah opened up about being at the top of

her game personally and professionally.

But first, that ring!

Showing off the 35-carat diamond and platinum sparkler

“with pride and happiness,” the mom of two joked about the attention

her brand-new bling is getting.

“Walking through a crowd with a ring on your finger and

a lot of bracelets is a little bit, you know, daunting,” she laughed.

“But it’s hard to take it off cause I love it so

much,” she added.

When it comes to wedding plans, Mariah said that while she

and James are looking to keep things “very private” and won’t be

hosting “tons of people,” the event will still showcase her trademark

glamour.

“I’m most excited about the grandeur, darling,”

Mariah smiled, clarifying that she and James are focusing on quality over

quantity for their special day.

“It’s not gonna be a big

wedding,” she said. “But it’s going to be grand.”

Adding, “I think the most important thing is the

relationship and, you know, just the connection. The love it of all. That’s the

most important thing, but of course I love a grand moment.”

While Mariah is keeping the details of James’ proposal to

herself for now, she did say she was “surprised” when the Australian

billionaire popped the question – and she preferred it that way.

“Darling, it’s my engagement ring, we can’t know when

it’s coming,” she told Scott with a smile. “We just have to receive

it.”

Besides walking down the aisle, Mariah is also excited to

hit the road.

“There’s a lot of nights, there’s a lot of cities,

there’s a lot of people and I’m just looking for a lot of joy,” she said

of her international tour.

“There’s something about doing both of those things,”

she said of performing across the globe and on the Las Vegas stage, “But

my favorite thing is being in the studio and recording and writing music.”

As for when fans can expect new songs, the superstar said

she wants to take her time perfecting an album.
