The eldest Jonas brother, Kevin Jonas, and his wife Danielle Deleasa, 26, have announced that they will be expecting their first child, E! News reported.
"I was overjoyed," Kevin revealed. "It's been the most exciting thing in my life so far... I'm excited and I'm nervous."
The young couple met in 2007 while on vacation in the Bahamas with their respective families.
They feature in Married To Jonas on the E! TV channel.
Kevin married former hairdresser Danielle in 2009 at Oheka Castle in New York's Long Island.
''We're at that [3-year] mark and people are like, 'All right guys, what's your plan? When are you going to have those grandkids?'," he said.
"I'm starting to feel that pressure a little bit.''
''Having kids is a big question right now; it does come up a lot,'' explained Danielle who has previously revealed the pressure that her friends have put on the couple in the past.
Pop group Jonas Brothers formed in 2005 and made their acting debut in Hannah Montana.
The band’s fifth studio album is due out later this year.
