Perhaps the Hanson brothers are trying to spawn a symphony orchestra.
Zac Hanson—the "littlest" member of the extraordinarily fertile pop trio—and his wife, Kate, welcomed their first child together, son John Ira Shepherd Hanson, Tuesday in Tulsa, Okla.
The little one weighed in at 8 pounds, 4 ounces.
"I am so overjoyed," Hanson, 22, told People. "There is not an audience or concert that could ever stand up to the feeling of meeting your baby for the first time."
"Shepherd [the parents' chosen moniker for their new addition] is the most wonderful gift we could ever receive. We're already enjoying every second of this great adventure," Kate added.
But Shepherd isn't going to be the littlest tyke in the Hanson family for long—nor will he ever want for playmates. Zac's older brother Isaac, 27, is expecting his second child with wife Nikki next month, and middle bro Taylor, 25, and his missus, Natalie, count three in their brood so far.
