R&B crooner Robin Thicke had to pull out of his performance in Los Angeles Tuesday night (Apr 6) as the opening act for Alicia Keys for “personal reasons.” Turns out, his wife, actress Paula Patton was having their baby!

Robin and Paula welcomed their first child, a boy, named Julian Fuego, into the world Tuesday, as confirmed by People.

“Mother, father and son are all doing well,” says Thicke’s rep. The crooner had canceled his portion of Tuesday night’s show at the Staples Center for “personal reasons.” But his tour mate, Alicia Keys, offered her congratulations from the stage.

A big congratulations goes out to Paula and Robin, who will celebrate their fifth wedding anniversary this June. Paula, 34, is also featured on the cover of the May 2010 issue of Ebony Magazine, where she talks about her relationship with Robin, 32, and their new baby, among other things.
