Zac Hanson has even more to sing about these days with his wife expecting their third child, according to Us Weekly.

The youngest member of the Hanson brood, who was only 11 when the group's single "MmmBop" was first released. He told Us he is excited about the news.

"We are so happy and thankful to add more life and love to our family!" he said to Us.

The singer, now 27, married his wife Kate in 2006. The couple already have two children, son Shepherd, 5 and daughter Junia Rose Ruth, 2, according to Us. Zac's older brother Isaac, 32, has two kids, with his wife Nicole. Taylor, 30, has five children with wife Natalie. Do we sense a future second-wave family band reincarnation here?

The Hanson brothers are scheduled to release a new album, "Anthem" June 18. The album's first single, "Get the Girl Back" was released in April.

But no song has meant as much to the former boy band's careers as "MmmBop" off their 1997 album "Middle of Nowhere." In ode to the chart-topping hit, the group unveiled their new beer, MmmHops, earlier this month at an after-party for the "Hangover III" movie premiere.

Hanson toured as a group in 2011 for The U.S. Musical Ride Tour to promote their 2010 album release "Shout it Out." Earlier in 2012, they performed tour dates with "Call Me Maybe" singer Carly Rae Jepsen before they picked their own tour back up to travel the world.

Hanson will tour this summer in support of "Anthem" and has already sold out two New York City dates at Irving Plaza. Drake Bell will join the group for some of their summer performances.
