Robin Thicke's son turns 3 next month, which probably means some fans are wondering when little Julian will be getting a younger brother or sister.  Well, call the baby-bump watch off, because Robin tells E! News that he and his wife Paula Patton are holding off on baby number two, at least for now.

Robin joked to E! that he won't start thinking about expanding his family "until my son has children." 

That said, Robin seems content to shower all his attention on his son.  "Being a father influences everything you do," Robin tells E!, explaining that being a dad has even impacted what he does in the recording studio. 

Julian "influences my lyrics…" Robin says.  "My last album [2011's Love After War] especially I wrote a few songs solely about him... But I don't really say it's about him."

Right now, Robin is "All Tied Up" with his role on BET's Real Husbands of Hollywood.  The show airs Tuesday nights at 10 p.m. ET.
