Stand back Isaac, Taylor and Zac there is a brand new addition to the Hanson clan!
The youngest member of the singing trio Zac, has welcomed his fourth child, a daughter with wife of 10 years Kate Hanson in their hometown of Tula, Oklahoma over the weekend.
Speaking about the joyous news to E! News Zac said of his newborn daughter ."We are overjoyed to share the arrival of Mary Lucille Diana Hanson. It is such an inspiration to meet her and to imagine all of the adventures we will take together as a family of six."
The couple's daughter joins the big family of older sister Junia Rose Ruth, 5, and brothers George Abraham, 2, and John Ira Shepherd, 8.
We wonder how long it will take the newest member of the Hanson family to be bopping ... literally to this worldwide hit!
