The Hanson clan just keeps growing!

Zac Hanson, the band’s youngest brother, and his wife Kate Tucker have welcomed their first child together.

John Ira Shepherd was born in Hanson's hometown of Tulsa on Tuesday.

While Shepherd is the first child for the 22-year-old drummer, definitely isn’t the first Hanson offspring. Middle bro Taylor and his wife Natalie have three children, Ezra, 5, Penelope, 2, and River, 1, while Isaac and his wife Nikki are parents to son Everett, 1, and are expecting their second child in the summer.

All eleven are expected to pile in one tour bus in support of the band's latest disc The Walk. They may want to spring for two!
