Chris Brown's baby mama's boyfriend just can't seem to stay out of trouble ... he's wanted by cops, the second time in just over a month.
King Ba was supposed to appear in front of a Texas judge Thursday on forgery charges but he was a no-show. The judge fired off a warrant for his arrest.
TMZ broke the story ... Ba was busted last month after cops claimed he forged more than $5,000 in U.S. Treasury checks. Police put out a warrant for Ba and he turned himself in after seeing his face on a local Crime Stoppers alert.
Looks like CB might have a leg up on baby mama Nia if she comes back at him in their custody battle.
