Kevin Jonas, one-third of the Disney Channel-approved band known as the Jonas Brothers, announced Tuesday that he was expecting his first child with wife, Danielle.
Kevin's brothers, Nick and Joe, immediately took to Twitter to express their excitement.
"Can't wait to welcome the newest addition of the Jonas family. Congratulations to my bro @kevinjonas & @daniellejonas," Nick Jonas, 20, tweeted Tuesday.
"Can't explain how excited I am about this. I'm going to be an uncle!" Joe Jonas, 23, wrote.
He later shared a joke Instagram photo of Danielle's "first ultrasound."
Kevin, Joe and Nick started a world tour on June 1 in Mexico. They're also working on their fifth studio album.
