Chris Brown not only has beef with his ex Karrueche Tran, but he also has problems with his daughter's mother!

Did Chris Brown Diss Karrueche Tran At The BET Awards Over The Weekend?

Since learning of his father status, the singer has been more involved in Royalty's life, but apparently Nia Guzman wants more money. She has also apparently been making it difficult for Brown to see Royalty.

According to TMZ on Wednesday, the singer has filed paternity documents in the state of Texas since that is where Royalty resides full-time with her mother.

The documents were specifically filed in Houston and they will get the ball rolling for Brown to ask a judge to document what he needs to give in child support and where things are with custody concerns.

Royalty's mother is apparently demanding $15K a month from the 26-year-old singer in child support, which Brown thinks is ridiculous.

Brown has been paying Royalty's mom every month what he believes is "a fair amount." Royalty's mom claims $2,500 a month is not nearly enough.

He wants a judge to set the figure and establish well-defined custody guidelines.

Despite all the problems he appears to be having with his daughter's mother, he has been taking on daddy duties well.

He had "daddy day" with Royalty and another little girl recently where they appeared to be enjoying a day outside.

It looks like Brown even took Royalty down by what looks like a lake some days ago.

He's definitely trying to spend as much time as possible with her.
