Isaac Hanson and his wife Nikki have welcomed a new addition into their family. Their new daughter, who they named Nina Odette, was born on March 11.

Nina will become a new sister to the happy couple’s sons, 6-year-old Clark Everett and 5-year-old James Monroe.

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

Hanson and his wife, Nicole Dufresne, were married in 2006. They met back in 2003, after Hanson spotted her in the crowd at one of his concerts.

Nina is the latest addition to the Hanson brothers’ blossoming family. Issac’s older brother, Taylor, is a father of five, and his other brother, Zac, also has three children of his own, according to Daily Mail.

The trio has sold 16 million records worldwide throughout the course of their career, which began in 1997. They will soon be embarking on a world tour for their upcoming album, Anthem.
