Middle musical Hanson brother, Taylor Hanson, and his wife, Natalie, welcomed their second child, a daughter, on Tuesday.
Mother and child, who was named Penelope, are both doing well, reports MTV News. No further details were made available.
The couple's son, Jordan Ezra, was born in October 2002, and when the boy was a year old, his father, now 22, told PEOPLE: "Having a baby is a life-changer. It gives you a whole other perspective on why you wake up every day."
As for how Hanson brothers Zac and Isaac are when it comes to relative responsibilities, Taylor replied: "They're awesome as uncles. But they haven't changed many diapers."
Hanson rose to fame during the summer of 1997, thanks to their single "MMMBop."
