Kevin and Danielle Jonas announced Tuesday that they will become parents. The “Married to Jonas” stars are thrilled after finding out the happy news.

"I was overjoyed," Jonas, 25, told E! News' Giuliana Rancic via Skype after finding out his wife was pregnant. "It's been the most exciting thing in my life so far. I'm excited and I'm nervous."

The Jonas Brothers member took to his Twitter account to tell his fans directly that he has a baby on the way. "It's true -- Danielle is pregnant! Can't even imagine how excited we are," he wrote. "I can't wait to share this with my best friend. I love you baby.”

Dani, 25, who is a former hairdresser from New Jersey, also shared in on the Twitter love, “I am so happy to tell everyone it's been so hard keeping this news in!!!”

Like the rest of the family, brother and bandmate Nick Jonas also took to the mini-blog to congratulate the couple. “Can't wait to welcome the newest addition of the Jonas family. Congratulations to my bro @kevinjonas & @daniellejonas,” he posted Tuesday.

The youngest JoBro added:

“I can't explain how i feel now #CongratsKevinAndDanielle”

“I'm just cry now #CongratsKevinAndDanielle”

“We can't wait for the baby  @daniellejonas & @kevinjonas #CongratsKevinAndDanielle :)”

“We are blessed, right? @daniellejonas & @kevinjonas :')”

Dani and Kevin were married at Oheka Castle in Long Island, N.Y., in December 2009 after meeting during a Bahamian vacation in 2007.

The Jonas Brothers -- Kevin, Joe and Nick -- began a world tour a month ago in Acapulco, Mexico, and will finish 30 shows later in St. Paul, Minn., on Oct. 8.
