“They and the whole family are delighted,” Douglas Rossdale said.
Reps for Stefani were not immediately available for comment.
According to Britain’s The Sun, the singer is 13 weeks pregnant. She has long said she’s wanted another child.
Stefani, 38, and British-born Rossdale, 40, wed in London in September 2002 and have one of the coolest kids in showbiz: Kingston Rossdale, who turns 2 on May 26.
Stefani has described Kingston as a “chilled-out little guy. He’s just like another person, except that he’s super-cute and super-entertaining.”
When it comes to his son, Rossdale recently said, “Finally, I got something right.”
Grandpa Rossdale sings Kingston’s praises too. “He is a great lad,” says the senior Rossdale. “And we are very much looking forward to another grandchild.”
