Which Jonas Brother Is Expecting a Baby?

Kevin Jonas is about to be swapping pop songs for lullabies!

The eldest Jonas Brothers member announced via E! News that he and wife of over three years, Danielle, are expecting their first child together. "I was overjoyed," Jonas said of learning that his spouse was pregnant. "It's been the most exciting thing in my life so far." Though, the 25-year-old did cop to being a little scared too, adding, "I'm excited and I'm nervous."

He later shared the big news on Twitter: "It's true — Danielle 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."

Kevin and Danielle, who goes by "Dani," have starred in their own reality show on E!, "Married to Jonas," since 2012, which has closely chronicled the duo's married life after their 2009 trip down the aisle.

In fact, a running storyline for the pair on the show has been the decision whether or not to have children. Kevin openly expressed his desire for kids, while Dani, 25, was a bit hesitant since she suffers from panic attacks and had been taking anti-anxiety medication to address the issue. But it looks like the New Jersey native successfully conquered her fears as she seems to be over the moon about her pregnancy.

"Iam [sic] so happy to tell everyone it’s been so hard keeping this news in !!!" she enthusiastically tweeted Tuesday.

Kevin's brothers Joe and Nick also took to Twitter to offer their congrats to the couple.

"Can't explain how excited I am about this. I’m going to be an uncle!" wrote Joe, while Nick said, "Can’t wait to welcome the newest addition of the Jonas family."

Dani and Kevin famously met while both were vacationing with their respective families in the Bahamas in 2007.
