And Elizabeth posted a photo of the beautiful newborn Friday on her own Instagram account. She captioned the image, "When she sleeps, I look at her pictures. I can't take my eyes off of our little gift from God! #BlakelyElizabethBrown."
"Elizabeth and I are so excited to be parents and start another caption in our lives. It has been a long journey to get here, but so worth it," Ty toldUs Weekly.
"We could not be more thrilled with the 7.5 lbs, 20 inch bundle of joy who has already got dad wrapped around her finger."
Both parents have ties to reality television, as Ty competed for Ali Fedotowsky's heart on Season 6 of The Bachelorette in 2010, and Elizabeth vied for Jake Pavelka's affection on Season 14 of The Bachelor in 2010.
"Elizabeth was a super mom and did a fantastic job during labor, as well as the past nine months in making sure that Blakely was as healthy as she could be. We are so very blessed," Ty told the magazine.
On April 20, Elizabeth shared a photo of herself lounging in a hammock and showing off her baby bump on Instagram.
"Any day now," Elizabeth, who celebrated her baby shower last month, captioned the picture.
The pair were so excited about the pregnancy because they had been trying for three years to conceive. Elizabeth and Ty's journey to parenthood also included one failed IVF attempt, so Elizabeth calls Blakely their "miracle baby."
The couple met at a charity event in Los Angeles and began dating in January 2013. Elizabeth and Ty got engaged nine months later and exchanged vows in March 2014.
