Kevin Jonas and Danielle Jonas have introduced their new baby to the world.
According to E! News, the "Married to Jonas" stars welcomed a baby girl named Alena Rose Jonas on Sunday.
"We are overjoyed at the birth of Alena Rose Jonas," the proud parents said. "She is precious! We could not be more excited to start building our family together. We want to thank our family and friends for their love and support, and our fans for all of their well wishes."
The proud first-time dad live tweeted the baby's birth after his wife went into labor. Eight hours later, he announced the arrival of their daughter and shared a picture of her wrapped in a white blanket and wearing a pink hat.
"On this day, a little star was born. Meet Alena Rose Jonas. #BabyJonas," Kevin tweeted.
In January, the couple told Us Weekly that they already had their first child's name picked out for some time.
"[The] middle name has a lot of meaning, but her first name is...different enough, but not totally out there. It's cute," the couple explained.
Kevin added: "I can't wait for Daddy days. I'm excited for the days I can just spend with her by myself. I want to take her to not typical little girlie things. I want to go to baseball games with her. Even just time at home -- me and her one-on-one while [Danielle] goes to the grocery store or out with her friends. Something to give her a break too. She deserves it."
In July, Kevin exclusively revealed to E! News' Giuliana Rancic that he was going to be a father and that he was overjoyed but nervous. Kevin and Danielle met back in 2007 while vacationing with their respective families in the Bahamas. They tied the knot about two years later at Oheka Castle in Long Island, N.Y.
The couple has partnered with Dreft's Amazing Baby Days app to "capture all of the amazing moments from their pregnancy through their daughter's first year."
