Mariah Carey has plenty of sweet, sweet fantasies, but having more children isn't one of them.
The 45-year-old singer -- who just got engaged to Australian billionaire James Packer last month -- opened up about the challenges of motherhood with The Lowdown's Diana Madison.

"It's hard," she revealed. "It only gets harder, but you know what? We make it work and we do our best."
Carey is the mother of 4-year-old twins, Monroe and Moroccan, with ex-husband Nick Cannon, and fears that welcoming another baby with Packer would make them very jealous.
"No, those are my two babies," she explained. "I think they would be so jealous because they get upset when I pet the dog."
When asked if either of her two kids have a singing gene, Carey said she thinks they do. And while she'd obviously love for them to follow in her footsteps, she just wants "them to be happy with whatever they do."
"I want them to be safe and protected and around good people," she continued. "But I want them to be happy."
Aside from caring for her kids and getting cozy with her new beau, the "#Beautiful" singer has been gearing up for her Sweet Sweet Fantasy European Tour, which kicks off March 15 in Glasgow, Scotland. Her Mariah Carey #1 To Infinity headlining residency is also playing out at the Colosseum at Caesars Palace in Las Vegas until Sept. 11.
So what's the secret to juggling motherhood and a massively successful career?
"It's not just ambition, but it's the love of music and entertainment," she explained. "That's always been what I love."
