Robin Thicke's drug issues may interfere in son's joint-custody

Robin Thicke's estranged wife Paula Patton may not allow the singer for their son Julian's joint custody if he is still drinking and taking drugs.

According to Radar Online, Patton is worried about Thicke being around their three-year-old son after he confessed his drug and alcohol revelations.

A source told the website that Patton will not allow the 37-year-old to be present in Julian's life if he was still drinking and using drugs.

The 'Blurred Lines' hitmaker recently revealed that Patton left him due to his drug issues.
