Tyrese is contesting a previous judge's order demanding he pay his estranged wife, Samantha Gibson Lee, $10,690 a month for child support.
TMZ reports the singer/actor has added famed attorney Ben Crump to his legal team and he wants a new judge to overturn the child support order.
The "Fast & Furious" actor filed an appeal this week, obtained by TMZ, that claimed Judge Farmer, who was presiding over the divorce, was clearly biased against him.
Tyrese said during a pretrial meeting in the judge's chambers, Judge Farmer apparently told him and his ex that he thought $10,690 per month in child support was appropriate based on the financial evidence and that he didn't care if Samantha was a "greedy, gold-digging bitch."
Tyrese claimed Judge Farmer already made up his mind even before hearing arguments and testimony in court.
The judge chastised Tyrese in open court when the actor raised his voice at Gibson Lee's attorney.
Tyrese said the judge cut him off in the middle of his answers, which Tyrese called totally outrageous. Tyrese claims his lawyer "definitely felt bullied by Judge Farmer" during the case.
According to TMZ, Tyrese has retained civil rights lawyer Ben Crump to assist his legal team.
