Three days after the 26-year-old former singer live-tweeted his wife Danielle Jonas' labor, he took to Twitter again to share his first father-daughter photo with baby Alana Rose.
In the pic, originally posted by Dreft, Jonas lovingly looks at his daughter while he holds her close to his chest.
After his daughter's birth on Sunday, Feb. 1, Jonas went to Twitter to share how he felt about the new lady in his life.
"I'm so in love with her," he wrote.
Jonas and Danielle married in 2009. Baby Alana Rose is the couple's first child.
