The new parents welcomed their first child together just a few weeks ago, but this is the first time Turner has acknowledged on social media that their bundle of joy, a baby girl named Willa, is here.
Nick Jonas wished his brother a happy birthday, too, with a silly clip of him dancing. "You’re the funniest person I know and I love celebrating you. I feel so lucky to have you as my brother. I love you so much. Happy birthday @joejonas," he said.
Kevin Jonas added, "Happy birthday @joejonas love you man. Hope you have an incredible day!!" and their father, Kevin Jonas, Sr., sent some adorable throwback photos from Joe's childhood out to the world with his birthday note: "A HUGE #happybirthday to @joejonas. Thanks for being born on our Anniversary and making our lives incredible. Love you my son."
