The ska band's guitarist Tom Dumont welcomed his third child on Saturday morning, according to a message posted on the group's official Twitter page.

"Koa Thomas Dumont was born this morning at 5am," the statement read. "Baby boy & parents are great. Looks like his brothers! One more No Doubt baby in the world!"

Dumont, 43, and his wife of six years, Mieke, are also parents to Ace Joseph, 4, and Rio Atticus, 2.

Dumont's new arrival is the latest addition to No Doubt's extended family.

In addition to Gwen Stefani's two sons, Kingston, and Zuma, bassist Tony Kanal and girlfriend Erin Lokitz are the proud parents of daughter Coco, while Adrian Young is dad to son Mason.
