The Jonas Brothers are expanding their family!

On Tuesday, Kevin Jonas confirmed that he and his wife Danielle Jonas are expecting their first child together.

Kevin tweeted, "It's true @daniellejonas is pregnant! can't even imagine how excited we are I can't wait to share this with my best friend. I love you baby."

The couple have been talking about starting a family together ever since they said "I do" in 2009. While the singer is "overjoyed," it's a big step for the pop star.

"It's been the most exciting thing in my life so far ... I'm excited and I'm nervous," Kevin told E! News about the baby.

Congrats to the happy couple!
