Chris Brown is asking a judge to force his baby mama to 'shut her trap'

According to TMZ, Chris Brown and his baby mama Nia Guzman will face-off in court today and one of the things Chris is seeking, besides 50/50 custody of his daughter, is for a judge to force Nia to shut up about the case. Read the report below..

"Chris wants the courts to do his dirty work -- as in, force baby mama Nia Guzman to quit bad mouthing him and talking about his fathering skills, or lack thereof, in public. Chris and Nia are heading into court Friday morning to start hammering out a formal custody agreement for Royalty, but sources connected to the case tell us job 1 will be a gag order. Brown filed docs for an injunction blocking Guzman from bashing him to news media and on social media.

Royalty's mom and dad have had very public beefs -- most recently when each accused the other of putting Royalty in dangerous situations. Sources close to Guzman say she thinks the gag order is a joke, since she only blasts Chris when he starts with her.   

Also on the table today -- custody time (he wants 50/50), and monthly child support (she wants $15k/month instead of $2,500/month). This case won't be quick and easy. As one source put it, "It's gonna get nasty."
