Jade, 30, gave birth to a baby girl on August 17, and she and Tanner, also 30, shared the big news with a series of adorable family photos Thursday night on Instagram.
"We did it! Our little sweetheart is here! She arrived on her own terms, quickly and 4 weeks early, but she is perfect in every way, healthy and doing well," Jade captioned an image of herself holding the baby in her hospital bed with Tanner by her side.
"Precious little girl, there are no words to describe the feeling of holding you in our arms for this first time and looking into your beautiful eyes. We love you so much. #bestdayever #ilovemyfamily."
Tanner also posted a photo of himself with the two loves of his life on Instagram in which the new parents are smiling ear to ear.
"Love My Girls... @babyjanner arrived this morning at 10:03AM... she decided to surprise us and come a little early... but mom and her are doing great... Best day of my life," Tanner captioned the picture on Thursday.
On Friday morning, Tanner also shared the sweetest photo of the baby and wrote "good morning" alongside it. Jade and Tanner's daughter has a full head of hair and little pouty lips.
Tanner and Jade told E! News through their representative yesterday, "She's here, our little sweetheart! Tanner and I are very proud to announce the arrival of our baby girl this Thursday morning. There's truly no words to describe the feeling holding you in our arms for the first time and looking into your eyes. We love you, precious girl."
The couple's daughter was reportedly born weighing 6 pounds and 8.8 ounces, and she measured 20 inches long.
In July, Jade celebrated both her baby shower with girlfriends and a romantic babymoon with Tanner in Hawaii.
The new parents announced they're expecting their first child in early March and revealed in May a baby girl was on the way.
Jade and Tanner met on Bachelor in Paradise in Summer 2015, got engaged during the show's finale in Mexico, tied the knot in January 2016 for a televised special on ABC, and then hashed out their issues when they appeared on Marriage Boot Camp: Reality Stars late last year.
