Zac Hanson of pop group Hanson and his longtime girlfriend, Kate Tucker, were to be married in Atlanta Saturday, the group's publicist said.
Hanson, 20, and Tucker, 22, were "planning an intimate ceremony with close family and friends," publicist Katie McNeil said in an e-mail.
Hanson and his brothers Isaac, 25, and Taylor, 23, formed Hanson in Tulsa. They are best known for their 1997 hit single, "MMMBop," which helped ignite the boy band craze.
