Mariah Carey is one demanding diva!

In her divorce, the singer reportedly asked Nick Cannon to give $5K a month to their kids' trust fund. However, the agreement stipulates that Mimi doesn't have the same financial obligation, reports TMZ.

According to the divorce docs, the songstress made a $6.3 million income in 2014, while Nick made $2.7 million the same year -- so we're scratching our heads wondering why the Nick has to put money into the trust fund, but Mariah doesn't.

The site also claims that a clause says that their twins, Monroe and Moroccan, are prohibited from calling either of the exes' future spouses "mommy or daddy."

Yikes!

After just six weeks of dating and a 10 year age difference, the hit maker and America's Got Talent host got married in the Bahamas in April 2008. The two confirmed that they had split in April 2014 (which means Nick doesn't get any of her Las Vegas residency money). They've remained close for the sake of their four-year-olds.

But it seems that the "Some Day" singer is making a lot of demands these days -- she's reportedly asked for an "inconvenience fee" of $50 million from ex-fiance James Packer.

No wonder she's single!
