Chris Brown and baby mama fight over child support, he says she's money hungry!

Over the weekend, Chris Brown's baby mama Nia Guzman told fans he doesn't give her money for their daughter, Royalty. TMZ just confirmed the news. Read their report below...

Chris Brown is at war with his baby mama, who claims he's stopped paying the measly $2,500 a month in child support, and now she's gunning for 6 times that.  

Multiple sources connected with the couple tell TMZ, Chris has been paying baby Royalty's mom, Nia Guzman, the $2,500, but the gravy train stopped in March. Our Chris sources say he stopped paying because Nia demanded $15k a month, which he thinks is ridiculous.

We're told Chris says Nia's treating the baby like a winning lottery ticket, but she claims he's being incredibly cheap and their daughter is suffering as a result. 

We're told Nia's lawyer, Carl Moore, will be filing legal docs in the next 2 weeks demanding back child support and a huge monthly hike.  

We're hearing rumblings of settlement.
