Nick Cannon has filed for divorce from Mariah Carey.

According to TMZ, the 'America's Got Talent' host reportedly filed the papers on December 12, just over a week after Mariah - who split from the TV personality in the summer after six years of marriage - was said to have been discussing terms of her property settlement with her lawyers.

The gossip website believes the pair - who have three-year-old twins Monroe and Moroccan - have agreed on a deal but also noted Nick won't be entitled to any of the 44-year-old singer's earnings from her upcoming Las Vegas residency.

The 'We Belong Together' hitmaker confirmed earlier this week she has signed up to headline the Colosseum at Caesar's Palace in Sin City and she is expected to receive more than $30 million for the run of gigs.

Mariah also revealed the Sin City crowd can expect to hear all 18 of her number one hits at her show.

She said: ''I'm going to do my first ever residency in Vegas at Caesars. This is a special event for me.

''And again, I have to hope that the fans will enjoy this cause I'm gonna be performing, which was kind of inspired by my album 'Number 1's', and this is now the updated version with 18 of them.''

Nick, 34, took to Twitter earlier this month to insist he will ''never say anything negative'' about his estranged wife and hopes they can both ''move forward'' this year.

He wrote: ''I will never say anything negative about @MariahCarey We are forever a family rooted in love.

''I am always an open book but Personal matters are just that 'Personal.' So please respect my family and respect the process.''

''I have no problem being painted as the bad guy. I got tough skin. Keep going! I just pray we ALL can move forward in the new year.''
