Hanson star Zac Hanson is set to become a father for the third time this Fall.
The youngest band member's wife, Kate, is pregnant with a sibling for their five-year-old son Shepherd, and two-year-old daughter Junia - and they couldn't be happier.
The Mmmbop hit-maker's tells People.com, "We are so happy and thankful to add more life and love to our family! It's fun this time to watch the little ones so excitedly anticipating their new sibling."
The upcoming months will be busy for the 27-year-old musician - he and his brothers, Taylor and Isaac, are set to release their new album, Anthem, in June, and they'll launch their 21st anniversary world tour and their own brand of beer, MmmHops, in the autumn.
