Kevin Jonas and his wife Danielle are expecting their first child together, a rep for the Married to Jonas stars confirms to Us Weekly. The "First Time" singer opened up about his wife's pregnancy during a chat with E! News on Tuesday, July 9. "I was overjoyed," Kevin said of learning his spouse is expecting. "It's been the most exciting thing in my life so far."

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

Kevin added, "I'm excited and I'm nervous." The couple met while vacationing in the Bahamas on May 23, 2007 and tied the knot two years later at Oheka Castle in New York's Long Island. The newlyweds honeymooned in Cabo San Lucas, Mexico.

While promoting their reality show in August 2012, former hairdresser Danielle opened up about their quest to become parents. "We're just waiting for the right time, and to have enough time to spend with the child and not miss everything about them growing up," the 25-year-old New Jersey native explained. "I think that's our biggest concern."

Kevin, 25, echoed his wife's sentiments during the FDNY City Harvest Food Drive for Hurricane Sandy Victims in December 2012. "We're waiting for the right time to start a family," he told Us. "We do want kids, but no baby news yet."

The Jonas Brothers -- Kevin, Joe and Nick -- are currently working on their fifth studio album. They kicked off a world tour in Acapulco, Mexico, on June 1. It will wrap up after 30 shows on Oct. 8 in St. Paul, Minnesota.
