The lines may be blurred between Robin Thicke and his ex-wife, Paula Patton, but his relationship with his young son, Julian, remains crystal clear.

The singer-songwriter took his son out for a supervised sushi lunch on Thursday (February 10) amid his custody battle with Patton, sharing a photo of himself and the young boy on Instagram.

Though the musician currently has a restraining order out against him that reportedly mandates he maintain a distance of at least 100 yards between him and his son, Thicke is allowed three supervised visits a week, according to court documents obtained by Entertainment Weekly.

Patton was granted the restraining order back in January after alleging that Thicke had assaulted her and had excessively spanked their child.
