Taylor Hanson welcomes baby no. 5: Wilhelmina Jane

Taylor Hanson, the middle brother of the '90s trio Hanson that we can all thank for the earworm "MMMBop," has welcomed baby  no. 5 to his brood with wife Natalie, the singer tells People.

"Natalie and I are thrilled to announce the arrival of our newest family member, Wilhelmina Jane Hanson. She arrived on Tuesday, Oct. 2, and was welcomed by more love than could fit in the room," says Hanson.

Wilhelmina joins older siblings Ezra, who is almost 10, Penelope, 7, River, 6, and Viggo, 3. Taylor is actually one of seven children. In addition to Isaac, Taylor and Zac, the trio that made up the Hanson brothers band, the three brothers have four younger siblings -- Jessica, Avery, Joshua and Zoe.
