Kevin Jonas surprised Jonas Brothers fans by marrying at the relatively young age of 22 in 2009. Now 25, Kevin and his wife, Danielle, are expecting.
"I was overjoyed," Kevin told E! of learning the news. "It's been the most exciting thing in my life so far."
"I'm excited and I'm nervous," he added.
Having a baby was often a topic of discussion on most recent episodes of their E! reality show, "Married to Jonas."
"We're just waiting for the right time," Danielle said last year, "And to have enough time to spend with the child and not miss everything about them growing up."
Both Kevin and Danielle tweeted enthusiastically about the news on Twitter Tuesday, with the trending hashtag #babyjonas.
