Nick Cannon is rumored to be begging Mariah Carey not to marry her billionaire Australian boyfriend James Packer.

Ok Magazine reports the "America's Got Talent" host "enjoys the rhythm he and Carey have raising their twins," not to mention he may still have feelings for his ex.

"He loves the co-parenting [to twins Moroccan and Monroe, 4] groove they've been in and he's worried that might change if she gets married to someone else," a source said. "He likes being the only man in Mariah's life. Friends even think he would get back together with her if he had the chance."

But indications are Cannon may no longer have that opportunity. Saluted as the fourth wealthiest man in all of Australia with a net worth of $4.6 billion, Packer is reported to be working on "over-the-top" wedding plans with the "Hero" singer. The two recently spent time on Packer's yacht in Ibiza, before embarking on an excursion to Israel for a getaway that was rumored to be a "pre-engagement meeting."

The pair met through mutual friend and filmmaker Brett Ratner, who works with Packer through his RatPac-Dune Entertainment movie financing operation.

After six years of marriage, Carey and Cannon split in 2014, with him citing irreconcilable differences in his divorce filing. Since then, Cannon has hinted that he may be hoping for a reconciliation.

When recently quizzed about a possible reunion, Cannon told reporters, "Um, yeah, you can never say never." As far as what he considers to be his best love advice, Cannon added, "Just go for it. Love hard."

Since the split, Cannon has been romantically linked with Sports Illustrated swimsuit model Jessica White, model and entertainer Amber Rose, and Eddie Murphy's ex-wife Nicole Murphy.
