This could be the beginning of a Hanson trio for a new generation.

Isaac Hanson and his wife Nikki welcomed their third child on Tuesday, March 11, their rep confirms to PEOPLE exclusively.

Weighing 7 lbs., 15 oz., Nina Odette joins the couple’s sons Clark Everett, who turns 7 next month, and James Monroe, 5½, at home in Tulsa, Okla.

“After more than five years of not having a baby in the house, having our first little girl is going to be fun,” the musician, 33, tells PEOPLE. “I know that Everett and Monroe are excited about being big brothers.”

Isaac, who’s the oldest of three Hanson brothers, is currently preparing to continue the group’s world tour in support of their sixth studio album, Anthem.

Younger brother Zac, 28, and wife Kate are parents to three children themselves: Shepherd, 5½, Junia, 3, and Abraham, 5 months, while middle brother Taylor and wife Natalie have five children: Ezra, 11, Penelope, 9 next month, River, 7½, Viggo, 5, and Wilhelmina, 17 months.

My friend @taylorhansonmusic is an avid photographer and film shooter, he’s also an HF user. On a recent trip we had a blow out in the middle of nowhere, so the first thing we did was strap up and go shoot! Anywhere and everywhere can be an adventure with the right attitude’
