Lauren Luyendyk and Arie Luyendyk Jr.’s dream family is complete.
Less than a month after the Bachelor Nation couple revealed Arie reversed his vasectomy, they announced that Lauren is pregnant with their fourth baby.
“Our last missing piece,” Lauren and Arie—who also share daughter Alessi, 5, and twins Senna and Lux, 3—captioned their joint Instagram post March 10, “coming this September.”
And to bring the exciting news to the world, the duo shared the most adorable pics of their family, dressed in all white, frolicking on the beach while Arie held a sonogram in his hand. Another photo also showed the twins cozying up to Lauren’s baby bump as they prepare to welcome their baby brother or sister.
The news comes just over two weeks after the duo—whose romance began on the 22nd season of The Bachelor, after which Arie broke up with final rose winner Becca Kufrin in favor of runner-up Lauren—revealed growing their family wasn’t completely out of the question (anymore).
“I’m getting a reversal,” Arie, 43, who got the procedure done in 2022, said in a recent YouTube video. “As you guys know I got the vasectomy after the twins were born. And ever since then, I don’t know. I think I rushed it. Honestly, it’s more on me, I think having the twins was hard at first.”
His wife of six years echoed his statement, revealing that her husband made the decision to get a vasectomy without consulting her when the twins were only six months old.
“He totally convinced me that chapter’s closed,” Lauren, 33, said. “And I’m like ‘Okay,’ and came to terms with that. And now I have to get out of that again. I’m getting there. Arie is totally there.”
From that moment on, it seems bringing another little one into the family was at the forefront of their minds.
“I kind of remember a moment of watching Senna and all of our kids are at the best age right now,” the auto racing driver explained. “I just felt like ‘Dang it, I think we could do this again.’ And if we had a singleton, we can totally handle that.”
Providing some not-so-subtle foreshadowing in her response, Lauren added, “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.
