Isaac Hanson's wife Nikki just MMMBopped out their third baby!

Isaac — the eldest of the three Hanson brothers — and Nikki are now parents to their first little girl. According to People, Nina Odette was born on Tuesday, March 11, weighing 7 lbs, 15 ounces.

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

Those boys are Clark Everett, nearly 7, and James Monroe, 5½; both go by their middle names, so we'll have to see if they do the same for the little lady.

Nina is just the latest addition to the Hansons' big extended family. Isaac's youngest brother Zac, 28, and wife Kate have three kids. Middle bro Taylor, 31, and his wife Natalie have five kids. Busy boys!

Check out an adorable Easter photo of Isaac, Nikki and their sons over here. If Miss Nina looks anything like her brothers, she's going to be the cutest little towhead.

Congrats to the growing family! What do you think of the name Nina Odette?
