Kevin Jonas and his wife Danielle Jonas have welcomed their second child.
"We are so excited to welcome our new baby girl, Valentina Angelina Jonas to the world today. She is healthy and beautiful and we couldn't be happier!" the pair said in a statement to People.
"Alena already can't wait for Valentina to come home and start being a big sister," they added.
Jonas later told his 5.18 million Twitter followers Valentina is "happy and healthy" and that he is "so in love."
His brothers Nick Jonas and Joe Jonas were among those to offer their congratulations online."Congrats Kevin and Dani! We have another Jonas!! Can't wait to meet that beautiful baby girl very soon @kevinjonas @daniellejonas," Nick wrote from Hawaii.
"Congratulations to @kevinjonas & @daniellejonas on the newest addition to the family! So beautiful!" Joe tweeted from Dubai.
The couple announced they were expecting again in April.
"We are excited to share the news that we are expecting a new addition to our family this winter," the pair said at the time. "Alena is beyond thrilled to be a big sister and we can't wait to meet the newest member of our family."
Jonas, Nick and Joe came to fame as the pop group Jonas Brothers and have since pursued solo careers.
Jonas last appeared on "The Celebrity Apprentice" Season 7 in 2015.
