Chris Brown is reportedly fighting to be named as the father on his daughter's birth certificate.

In March (15), the Kiss Kiss hitmaker was hit with reports suggesting he had fathered a baby girl named Royalty with a 31-year-old model named Nia.

Brown has since confirmed he is the dad, but Nia's current partner, Brazil Riesling, has been named as the biological father on the birth certificate, according to TMZ.com.

The website adds that Brown has been in touch with his lawyer, and is attempting to persuade Nia to put his name on the legal document.
