Chris Brown, Nia Guzman and baby Royalty

Chris Brown is taking his baby mama to court to put a formal child support agreement in place, where she could get less money, because he believes she blabbed.

According to, the 25-year-old singer didn’t know he was the father of 9-month-old Royalty until last month, when former model Nia Guzman told him.

After finding out, Brown quickly agreed to pay monthly child support to take care of both Royal and Nia –substantially higher than he’d be required to pay in court, in exchange for her silence.

Now that the word is out, he believes Nia leaked the stories, so his legal team is prepping documents to put a formal support payment in place, but he’ll pay less than he does now.
