Kevin Jonas gave fans a first glimpse of his new daughter Valentina on Sunday.
"Say hello to my newest love Valentina," he captioned a photo of himself gazing adoringly into his daughter's eyes.
Jonas had confirmed through his rep Thursday that Danielle gave birth to Valentina the same day.
The former "Married to Jonas" stars married in Huntington, N.Y., in 2009, and are also parents to 2-year-old daughter Alena.
"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 at the time."Alena already can't wait for Valentina to come home and start being a big sister," they added.
Jonas' brothers Nick Jonas and Kevin Jonas were among those who offered their congratulations online. The trio of siblings came to fame as the pop group the Jonas Brothers and have since pursued solo careers.
"Congratulations to @kevinjonas & @daniellejonas on the newest addition to the family! So beautiful!" Joe tweeted.
Jonas had told Parade magazine after Alena's birth that he was more than willing to share the first photos of his daughter online. The star explained he and Danielle wanted to be in control of the pictures and circumvent leaks.
