Paula Patton is accusing Robin Thicke of abusing their 6-year-old son, Julian Fuego.

According to the New York Daily News, the actress filed court docs asking a judge to limit the singer’s interaction with their son due to his “excessive spankings” as a form of discipline.

In a court declaration, Robin said, “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.”

He added, “This is the type of discipline to which Paula and I agreed during our marriage. I have never exceeded age-appropriate discipline, and thus never been an issue, nor has it been raised by Paula previously.”

It’s definitely an issue now.

Last week, an investigation was launched by the Los Angeles County Department of Children and Family Services after Julian told his school about his spankings.

Robin told the judge Paula sent him a text on January 5 that read, “Julian is afraid of you.”

He also claimed his ex-wife “holds residual anger” because he didn’t invite her to his father’s funeral last month.

The judge denied Paula’s request to limit Robin Thicke’s interaction with their son.
