Robin Thicke sparked another row with his ex-wife Paula Patton after he declined the chance to see his six-year-old son on Saturday (28.01.17).

The 'Blurred Lines' hitmaker had a supervised visit with Julian on Friday (27.01.17), but reportedly passed up the opportunity to spend more time with him the following day, thereby reigniting the bitter feud between himself and the 41-year-old actress.

A source close to the situation said: "He did not exercise his right to spend time with his son and the monitor on Saturday, citing a business meeting. However, Paula offered alternate times that Julian could see Robin with the monitor that weekend, but he declined all visitation.

"These are the actions of a father who claimed he wanted to spend time with his son."

Despite this, an insider insisted Robin remains "focused" on his son as he prepares to return to court to continue their bitter custody battle on February 24.

The source told People: "[Paula] keeps trying to bury him, and this is a concerted effort to prejudice the public against him. He has taken no such campaign against her.

"He's taking this extremely seriously, and it's unfortunate and very difficult when you're on the receiving end of a campaign of negativity."

Last week, a judge in Los Angeles gave Paula sole legal and physical custody of Julian, while Robin was granted supervised visitation rights, meaning he could spend three days a week at a neutral location with his son until the next court hearing.

However, under the temporary restraining order taken out against him, Robin is still required to stay 100 yards away from Paula, her mother and Julian the rest of the time.

And in documents handed to the court last week, the '2 Guns' actress alleged that her ex-husband - who she divorced in 2015 - physically abused her, was unfaithful and struggles with drug and alcohol addictions.
