The boyfriend of Chris Brown's baby mama just learned a very expensive lesson -- showing up late for court can cost you tens of thousands of dollars.
King Ba, who was dating Nia Guzman when Royalty was born, missed his scheduled hearing in his check forgery case last week. As we reported, the judge issued an arrest warrant. A source connected to Ba tells us he eventually showed -- a day late, and the judge raised his bail from $5,000 to $40,000 as a penalty for his tardiness.
Ba paid immediately, but then ran into more problems because he had a Cali medical marijuana card. The judge called BS since Ba lives in Texas, and we're told he now has to undergo 5 drug tests, and can't leave Harris County.
All because he was late for court. Set an alarm, bruh.
