The Hanson family is expanding again!
"We are so happy and thankful to add more life and love to our family," Hanson, 27, told the magazine. "It's fun this time to watch the little ones so excitedly anticipating their new sibling."
The new addition will join other brother Shepherd, 5, and sister Junia Rosa Ruth, 2. The couple married in 2006.
Hanson is the youngest member of the famous family trio, who are releasing their latest album, Anthem, on June 18.
