"Welcome to the world Livvy Rowe Luyendyk," Lauren and Arie wrote in a joint post.

The couple revealed Livvy was born on September 18, and they added, "Love you our sweet little angel girl!"

The post included several photos of the happy parents holding their new baby, who was swaddled in a white blanket and wearing a pink headband with a big bow on it.

Lauren also took to Instagram Stories and gushed, "Head over heels for our little gal. Feeling blessed beyond measure."

And Arie, resharing the solo picture of himself with Livvy, wrote via Instagram Stories on Monday night, "The best birthday I could have asked for! What an incredible day, so proud of you [Lauren]!"

Bachelor Nation rushed to the comments to congratulate the proud parents -- including Hannah Ann Sluss, Amanda Stanton, Tenley Molzahn, Raven Gates, Tia Booth, Jared Haibon and JoJo Fletcher.

Arie and Lauren revealed Baby No. 4's gender on April 16 in an Instagram video that also featured their three children -- daughter Alessi, 6, and four-year-old twins Lux and Senna.

In the video, Arie and Lauren popped two giant black balloons that released pink confetti into the air.

Arie told their kids, "You're going to have a sister," before kissing his wife.

The family then enjoyed some white cake with pink filling as part of the celebration.

The couple also shared in a YouTube video at the time how they conceived after Arie had a vasectomy reversal in 2024.

Although Arie had the procedure done in Summer 2024, he didn't open up about his vasectomy until February of this year.

After experiencing a chemical pregnancy, Lauren said earlier this year that she was "super excited" about giving birth to the couple's "last baby."

Arie and Lauren got married in January 2019.

Arie and Lauren announced they were expecting their first child together in November 2018 and revealed two months later that Lauren was pregnant with a daughter.

Lauren gave birth to Alessi in May 2019, just four months after she and Arie tied the knot at Haiku Mill in Maui, Hawaii.

Lauren went on to suffer a miscarriage in May 2020, but she and Arie announced in December of that year that Lauren was pregnant again, with twins this time. The following month, the couple revealed they had a baby boy and a baby girl on the way.

Senna and Lux were born in June 2021.

After having three children, Arie made it clear in a video that he was done having kids, and then he had a vasectomy in January 2022.

Lauren had finished Arie's season of The Bachelor in second place when Arie actually chose Becca Kufrin as his winner and popped the question to Becca during the Final Rose Ceremony, which aired in March 2018.

But weeks after getting engaged, Arie decided to dump Becca because he claimed he was still in love with Lauren, and then he begged Lauren for a second chance.

Once Lauren took the former racecar driver back, Arie proposed marriage in March 2018 on The Bachelor: After the Final Rose after Season 22 aired on ABC.

Arie and Lauren subsequently moved into their first home together in Phoenix, AZ, in April of that year. They went on to split their time between Arizona and Hawaii.
