To mark the occasion, Owen posted a sweet photo from a shoot the pair did with their newborn, marking the world's first official glimpse at baby Paris.
The shot sees Hartlein cradling her baby girl in her arms as she shares a kiss with Owen, who holds a balloon reading "Paris Hartley Owen."
"What a Mother’s Day it is... pretty special first Mother’s Day for [Erica Hartlein] and myself with our new little nugget Paris Hartley Owen," Owen captioned the image.
The "Down to the Honkytonk" singer also shared a Mother's Day post honoring his own mom, writing, "My mom is the most selfless, beautiful human being I’ve ever known... From driving me to baseball games as a kid, to riding with me to Nashville, TN when I dropped out of school...she’s never been anything but supportive and loving. I’m proud to be a mamas boy. Happy Mother’s Day to every mother out there."
Owen announced his daughter's birth with a tweet on April 29, which means the infant shares a birthday with country icon Willie Nelson.
It's a Willie great day!!
Well Happy Birthday to @WillieNelson born on this day April 29th, 1933.
Also, happy birthday to my little beautiful daughter, Paris Hartley Owen born today April 29th, 2019.#GodIsGreat— Jake Owen (@jakeowen) April 29, 2019
Along with Paris, Owen is also dad to 6-year-old daughter Olive Pearl, who goes by her middle name, with ex-wife Lacey Buchanan.
“To be blessed with another beautiful little girl is a big deal because I do think that it takes special men to be a great dad to a little girl,” the 37-year-old told PEOPLE. “And I feel like, thanks to Pearl, she’s shown me how to be a good father to little girls, and I’ll be a great father to Paris because of that.”0comments
He added that the prospect of welcoming a second child was “just as exciting” but that he was “more calm this time” since he already has parenting experience.
