Singer Taylor Hanson is set to become a father again. The MMMBop hitmaker's wife Natalie is pregnant with the couple's fifth child. The former child star tells People.com, "Natalie and I are so anxious to meet our fifth mini-Hanson." 

The couple, who wed in 2002, is already parents to Ezra, nine, Penelope, six, River, five, and Viggo, three. 

The year will be a busy one for Hanson - the musician and his singer brothers Issac and Zac are currently in the middle of their Shout It Out World Tour.
