Welcome to the joys of fatherhood, Arie Luyendyk Jr.
"We never knew we could experience a love like this," the couple said in a joint statement to E! News. "We cried, we laughed and we are so happy she is healthy and doing so well. It's amazing to see this tiny person that is half of each of us. She has Dad's hands and finger nails and lot of Mom's facial features."
While mom and dad have been able to share a few special moments on social media, fans may want to follow another account.
Believe it or not, baby Alessi already has an Instagram and she has a whopping 286,000 followers and counting.
It's a special new chapter for a couple who found love in an unconventional way. But throughout the wild ride, both Arie and Lauren have been thankful that they found each other.
"A year ago today I got engaged to the love of my life while the world watched. Our story is pretty unconventional, but it's ours," Lauren previously shared on Instagram. "Grateful for @bachelorabc bringing us together, because he's the best thing that ever happened to me."
In honor of their latest milestone, we're compiling all of Arie and Lauren's sweetest photos of their baby girl in our gallery below. We're not saying everything is coming up roses, but life looks pretty darn sweet for this Bachelor Nation couple.
Congratulations you two! We can't wait to see more.
