Chris Brown has had a hard time resisting the urge to take personal matters to social media as of late, and his recent legal filings to establish paternity for his child have found him caught battling with the mother and grandmother of his baby girl on Instagram.

Nia Guzmaan, the mother of Royalty (Chris' daughter), was said to be looking for $15,000 a month from Chris, which the singer apparently felt was too high-- pushing him to file legal documents on the matter.

When Baller Alert reported on the news, Nia's mother jumped into their comments, calling the reports false, and suggesting that Royalty needs both private schooling and to live in a gated community for her safety.

This then threw Brown into a rant in the comment section, this time arguing that Nia was looking for $4,000 a week for the child, claiming that he has custody of Royalty for two weeks out of every month.

After watching all this happen, Nia then weighed in, for the most part just telling everyone else to stop sharing their business on social media, before laughing off Chris' claims that she requested that much money, and that he spends half of every month with Royalty.
