And their second wedding will be even bigger than their first! A different insider tells Life & Style that "Mariah will have a party in St. Tropez, France, or Italy’s Amalfi coast with 500 guests, including Beyoncé and Elton John. They’ll have $1,000-a-bottle Angel champagne, plus a 5-foot cake dusted in real gold.”

And don't expect the diva to go skimpy with her jewels. The singer will spend upwards of $250k on a diamond-encrusted dress, and has a special performance planned for attendees. “Mariah’s singing at her wedding,” the insider adds. “She’d never hire another star to outshine her.”

Despite the fact that Mariah got engaged following their split and Nick welcomed a son with ex-girlfriend Brittany Bell, the duo feels "like they belong together," the first source shared. "Mariah wants to get married again, and thinks Nick is the one."

The former America's Got Talent host previously opened up about how the couple was able to maintain such a healthy co-parenting relationship. "You put the kids first, but then when you understand that you have unconditional love for these human beings and you want the best existence for them, then you put whatever differences you may have had aside," he said.

"A lot of times when you think about breakups in relationships, it's usually over ego. And if you can remove your ego from that, and make it about your loved ones, then that's what it's about," he added.
