Robin Thicke & Paula Patton’s Custody Battle Gets Ugly Over Shocking Abuse Claims

Robin Thicke and ex-wife Paula Patton are in a bitter custody battle over their son Julian.

In new court documents obtained by “Extra,” Paula is making explosive abuse claims about her ex, who she says has been physically rough with their son.

She also claimed that Julian is “scared" of Robin. According to a school official's declaration, Julian revealed that Robin frequently “punches” him hard. The day before he told the school official, Patton claims that Julian demonstrated how hard he was spanked by Robin.

Patton filed an emergency order to limit Robin's time with Julian, but the family law judge denied her request on Thursday.

Thicke is denying Patton's allegations, saying in his own declaration, "On a very rare occasion and only as a last resort, I will use light spanking, but it is consistent with the law — open hand on the butt. This is the type of discipline to which Paula and I agreed during our marriage.”

Robin claims that Patton's legal move is in retaliation for her not being allowed to attend his dad Alan Thicke's funeral. He said, "Paula did not have a positive relationship with my father and often made negative comments to me about my father. As such, she was not welcome at his funeral.”

Last year, Paula opened up about co-parenting with Robin with “Extra's” Mario Lopez at Universal Studios Hollywood. Watch!
