Taylor Hansen

Hard to believe, but Taylor Hanson – whom most of us still remember as one of the blond brothers singing “MMMBop” in the ‘90s as part of boy band Hanson – will soon be a dad of five! The 29-year-old and his wife Natalie, 28, who married when they were just 19 and 18 respectively and are already parents to 9-year-old Jordan, 7-year-old Penelope, 6-year-old River, and 3-year-old Viggo, announced earlier this year that baby number five is on the way! "It is an incredibly inspiring and challenging job being a parent, and as it turns out, being young really helps you keep up,” Hanson told Parenting.com last year.
