Talk about a doting daddy.
Robin Thicke couldn't hold back his excitement over 2-year-old son
Julian Fuego, when he appeared at a VH1 Save the Music Foundation event at Chicago's Paris Club's Studio Paris with wife Paula Patton.
"He talked about Paula and showed off cell phone pictures of his son to everyone," an attendee tells PEOPLE. "He was great. He did a meet-n-greet with a contest winner and was joking around with the staff. Whenever anyone asked him about his family, his eyes lit up and he got very chatty."
Thicke, who was at the event for the organization's 2012 Songwriters Music Series, performed an acoustic set of his hits and even included a sexy cover of Marvin Gaye's "Sexual Healing." – Dahvi Shira
