Chris Brown's baby girl answers to Royalty!
We've learned Nia named the kid Royalty. What we don't know ... whether she consulted Chris before inking the birth certificate.
TMZ broke the story ... Chris and Nia got it on summer of 2013 and she gave birth 9 months ago. As we reported, Karreuche was blindsided ... she had no idea until minutes before TMZ posted the story Tuesday afternoon.
As for Chris' involvement ... we're told he calls Nia regularly and now says he wants to openly participate in raising the baby. Nia and Royalty live in Texas, and Chris says he'll gladly fly there regularly to parent her.
And the Chris Brown baby daddy saga continues.....
