The extended Hanson brood has a new member! Isaac Hanson and wife Nikki welcomed their third child, daughter Nina Odette, on Tuesday, March 11.

Their rep confirmed the news of the bundle of joy's arrival to PEOPLE.

Little Nina was born at home in Tulsa, Okla., and she weighed in at 7 lbs., 15 oz. She joins big brothers Clark Everett, who will be 7 in April, and James Monroe, who is 5.

The eldest Hanson brother, 33, is excited about both having a daughter and the excitement and chaos a newborn brings to the home, saying, "After more than five years of not having a baby in the house, having our first little girl is going to be fun. I know that Everett and Monroe are excited about being big brothers."

The proud papa will return to the road with his brothers in support of their sixth album 'Anthem' shortly.

When we said brood, we weren't kidding. The Bros. Hanson each have several children. In addition to Isaac's three kids, middle brother Taylor, 31, has five kids with wife Natalie and youngest brother Zac, 28, has three children with wife Kate.
