Zac Hanson has welcomed his third child into the world.

The Hanson drummer's wife Kate gave birth to a baby boy named George Abraham Walker on October 17, he has confirmed. "We are very excited to share the addition of George Abraham Walker Hanson to our growing family. Abraham is healthy and we are happily sharing a little down time together as a family," Zac told People.

The couple's latest bundle of joy joins their eldest son John Ira Shepherd, five, and their only daughter, Junia Rosa Ruth, two. The 28-year-old star - who found fame with his brothers Isaac and Taylor in the 1990s following smash hit song "MMMBop" - noted that the tot will go by his middle name, Abraham, and weighed 8 lb, 7 oz at birth.

Earlier this year, Zac gushed that his wife's latest pregnancy was made all the more enjoyable as his eldest children couldn't wait to meet their new brother. "It's fun this time to watch the little ones so excitedly anticipating their new sibling," he said. The latest addition brings Hanson's collective number of children to 10. Zac's eldest sibling and bandmate, Isaac, 32, has two children - Everett, six, and Monroe, four. Meanwhile, 30-year-old Taylor has five children: Ezra, 10, Penelope, eight, River, six, Viggo, four, and eight-month-old Wilhelmina.
