Taylor Hanson, the middle brother in the band Hanson, and his wife, Natalie, have welcomed their third child, a son, the band announced on its official Web site.
River Samuel Hanson was born on Sept. 4, in Tulsa, Okla. "River is an incredible addition to our family," the new dad says in the Web posting. "We could not be happier!"
The couple, who wed in June 2002, are also parents to son Jordan Ezra, born in October 2002, and daughter Penelope, born April 19, 2005.
When Jordan was only a year old, his father, now 23, told PEOPLE, "Having a baby is a life-changer. It gives you a whole other perspective on why you wake up every day."
