Robin Thicke had good reason for canceling his portion of a show with Alicia Keys Tuesday evening!

He and actress wife Paula Patton welcomed their first child, son Julian Fuego, on Tuesday, April 6th in Los Angeles, PEOPLE has confirmed exclusively.

“Mother, father and son are all doing well,” says Thicke’s rep, while Keys offered her congratulations from the stage.

Grandfather Alan Thicke says Julian “already has Robin’s voice, Paula’s sense of drama – he arrived a little early – and my hair.”

Leave your best wishes for the couple at the left!
