Nick Cannon's been in the news lately for challenging his old rival Eminem to a $100,000 rap battle.
Nick and Em's aged beef started over Cannon's wife Mariah Carey -- who separated from Cannon in 2014.
However, Cannon and Carey are still not divorced, because Nick refuses to sign the paperwork.
According to TMZ, Cannon still loves Mariah, and by not signing it prevents her from marrying her current fiance, Australian billionaire James Packer.
Carey is said to be frustrated with the situation.
It all sounds like good ammunition for Shady if decides to step in the lyrical ring with Cannon for 100k.
