The 36-year-old singer raises son with his actress wife Paula Patton, reported People Magazine.
"He's obviously the best thing that's ever happened to me. He's my good luck charm," he said.
Thicke is currently topping charts and has received nominations for 'Blurred Lines' video. He says his son wants to follow his footsteps.
"He's three and wants to be a rock star! He's always talking about hooking up with the band. He tells me he's going to New York and 'They're going to pay me, Daddy!' It's cute and adorable," he said.
