There’s another little MMMbopper in the family!

Zac Hanson, 28, and his wife Kate, 29, welcomed a son named George Abraham Walker on Thursday, Oct. 17, a rep confirmed to PEOPLE.

The baby, who will go by his middle name, joins big brother John Ira Shepherd, 5, and sister, Junia Rosa Ruth, 2½.

“We are very excited to share the addition of George Abraham Walker Hanson to our growing family,” Zac said in a statement. “Abraham is healthy and we are happily sharing a little down time together as a family.”

And Zac isn’t the only one in the Hanson clan with a growing family. His brother Taylor has five children and Isaac has two of his own.

Guess they’ll need a pretty big table for Thanksgiving dinner!
