Arie Luyendyk Jr. and Lauren Burnham are expanding their brood.
Just two months after The Bachelor alums—who also share kids Alessi, 5, and twins Senna and Lux, 3—revealed Arie had undergone a vasectomy reversal to try for another kid, they have revealed their fourth baby’s sex.
In an adorable video of the family shared to Instagram April 15, Ari and Lauren wrote in the caption, “The baby is a…”
The ensuing clip shows the soon-to-be parents of four popping balloons to reveal pink confetti, revealing they will be having another baby girl. In another photo of the family indulging in pink cake, the couple gushed in the caption, “We can’t wait to meet you baby GIRL.”
And the baby’s sex was a shock to both Arie and Lauren, who donned blue clothing for their party and guessed in an earlier video they were going to have a boy.
“I think it’s a boy,” Ari explained in a video shared just before their sex reveal. “This pregnancy feels different so, team boy.”
Lauren, for her part, concurred, adding, “If my instincts are wrong, I’m going to be so shocked.”
But now that they know their baby’s sex, Arie and Lauren are sure their family is complete. After all, they noted in their March 10 pregnancy announcement that their fourth baby is their “last missing piece.”
Of course, Arie and Lauren—who tied the knot in 2019 after meeting on season 22 of The Bachelor—had thought they were done after welcoming Senna and Lux. Indeed, the professional auto racer underwent a vasectomy in 2022, believing their family was complete.
“I think I rushed it,” the 43-year-old reflected after telling fans he would be getting a reversal procedure. “Honestly, it’s more on me, I think having the twins was hard at first.”
Meanwhile, Lauren, 33, had already come to terms with being a mom of three, but was more than open to try for just one more. As she put it, “Hopefully baby no. 4 coming soon.”

Instant Chemistry
Lauren, a 25-year-old tech salesperson from Virginia, is cast as one of 29 women competing for 37-year-old Arie’s heart on season 22 of The Bachelor, which begins filming in Sept. 2017. Even from the first night, the pair is practically inseparable as they get to know each other.
A Tough Goodbye
The couple’s love story seemingly comes to an end in Nov. 2017 when he proposes to Becca Kufrin, despite telling Lauren he loved her on their final date in Peru. A month later, Arie tells Becca he’s second-guessing his decision and reaches out to Lauren via Instagram. Meanwhile, The Bachelor premieres on Jan. 1, 2018.
Facing Reality
Cameras roll as Arie officially calls off his and Becca’s engagement during one of their “Happy Couple” getaways in early January. Bachelor Nation slams Arie for allowing the breakup to be filmed, and one day later a source tells E! News he flies to Virginia to tell Lauren he wants to give their relationship another shot.
Finding Closure
In March, Arie and Becca sit down for the first time since their breakup at the live After the Final Rose special. She tells him he “robbed” her of first proposal and engagement, adding, “I do want you to be happy. I hope that Lauren is your one and that you have found that happiness with her. I just want you to be honest with her and hold her heart high, have the most respect for her, be committed to her.”
One More Chance
Arie proposes to Lauren on the After the Final rose special, telling his new fiancée, “I have made some bad decisions, but the best decision was running back to you. I can’t imagine a life without you. You have shown me a love that is patient, a love that is kind, and I truly believe you are my soul mate. I’m ready to face this life with you and all that comes with it. Good and bad. I love you so much. And I want to do this in front of everyone because I want to show you that I should have done this a long time ago.”
Her response? “Definitely!”
Post-Engagement Bliss
The lovebirds celebrate their engagement with a trip to Europe, where photographers capture Arie and Lauren packing on the PDA.
Back to the Beginning
In June 2018, Lauren reflects on the day she was introduced to Arie at a racing event in Dallas—months before signing up for The Bachelor! “Met this stud here exactly a year ago today,” she wrote on Instagram.
Home Sweet Home
After relocating to Arie’s native Arizona, the couple officially become homeowners after purchasing an $870,000 home in Phoenix. “Arizona has been a really easy adjustment for me as I’ve moved around my whole life,” Lauren shares with Us Weekly. “I’ve been making friends and trying to get settled in, but we really haven’t been here all that long yet. It has been fun exploring the area, and Arie is a really good tour guide, so that helps.”
There’s a Bachelor Baby On Board!
In November, Arie and Lauren reveal she’s pregnant with their first child—a baby girl! They create an Instagram account for “Baby Luyendyk,” where the mom-to-be details her pregnancy journey with fans.
Last Fling Before the Ring
Several members of Bachelor Nation attend Arie and Lauren’s co-ed bachelor/bachelorette celebrations in Las Vegas. “Fresh flowers were everywhere. And a cake, cupcakes, and edible icing flowers—it was SO good! I was in heaven,” the bride-to-be tells E! News of their experience at The Venetian.
