Cops Called to Paula Patton's Home as Custody Battle With Robin Thicke Escalates

The custody battle between singer Robin Thicke and ex-wife Paula Patton is heating up after cops were dispatched to the actress' Malibu home over the weekend.

In video obtained by TMZ, Patton looked distraught as she was questioned by sheriff’s deputies Friday. Thicke was also there, but out of frame in the exclusive video.

The “Blurred Lines” singer reportedly asked police to go to the house after his ex allegedly refused to let him see their six-year-old son, Julian, during a regular custody visit.

In the video, an officer was recorded saying: “We're gonna say we spoke to the child. The child said he did not want to go. And that's the end of it.”

The drama comes as Patton accused Thicke of physically abusing Julian, claims which Thicke denies.

Court documents obtained by Inside Edition she claimed the "physical abuse" has left Thicke's son "fearful of [his father]."

The documents allege Thicke "punches him so hard, but never where someone can see." They also allege he showed up drunk to his son's kindergarten graduation last June.

Patton asked the court to limit visitation between the singer and their son to "monitored daytime visits only." The request was denied.

Thicke is denying all allegations, saying in a statement: "On a very rare occasion, and only as a last resort, I will use light spanking. This is the type of discipline to which Paula and I agreed during our marriage."

California law allows parents to spank children. As long as the spanking is done with an open hand on the buttocks and doesn't cause physical injury, there is no violation of the law. But punching is unacceptable.

Thicke says his ex-wife is making false charges in retaliation because she was not invited to the funeral of his father, Alan Thicke, last month.

He said he had a legitimate reason for the snub.

He said: "Paula often made negative comments to me about my father. As such, she was not welcome at his funeral."

Although the court ruled in his favor, Thicke is still under investigation by the Department of Children and Family Services.
