Chris Brown's baby mother wants supervised visitation for the star

The mother of Chris Brown's baby daughter has filed court papers seeking supervised visitation for the singer amid fears for her child's safety.

The Loyal hitmaker recently asked a judge in Houston, Texas to establish official paternity of one-year-old Royalty so he can fight for joint custody with the girl's mum, model Nia Guzman.

He also wants to reduce Guzman's request for $15,000-a-month in child support, which he believes should be closer to the $2,500-a-month he currently pays.

However, Guzman is preparing to challenge his custody demands by raising concerns about Brown's maturity. She is reportedly worried her one-time fling is not responsible enough to look after a child on his own, and has requested he only be allowed visitation if he is supervised, according to TMZ.com.

The judge has yet to rule on the two parties' requests.
