The hit-making singer and his three-year-old were spotted leaving their Manhattan hotel together on Friday (13 December) and we can't help but notice how much of a little rockstar Julian already appears to be.
Holding tightly onto his dad's hand, Julian hit the streets of NYC in an all red Adidas tracksuit, reminiscent of the sporty outfits worn by hip-hop group Run DMC.
He also wrapped up with a black scarf and hat and completed his look with a pair of red trainers.
Meanwhile, 36-year-old Robin oozed sophistication and style in a pair of black, wax-effect jeans, some black trainers and a camel coloured overcoat.
Absent from the twosome's side was wife and mum, Paula Patton, who Julian was seen shopping for Christmas presents with in Beverly Hills last week.
Actress Paula, 38, recently unveiled an edgy new bob haircut and has been working the striking 'do with various cool ensembles over the past month.
Great fashion sense certainly runs in the Thicke family!
Robin and Paula married in 2005. The couple were teenage sweethearts.
