The Luyendyk Family Is Expecting a Baby in September

“Our last missing piece… coming this September,” the couple revealed in a March 10 Instagram post.

The initial photo in the Luyendyk family’s announcement post showed the couple and their three children together on the beach. Everybody wore cream-colored sweaters along with jeans.

The three kids ran around as the family patriarch held onto an ultrasound photo. The couple smiled as they watched their children.

The second photo in the Instagram post showed the couple’s twins, Lux and Senna, snuggled up to their mom’s baby bump. Senna placed a hand on her mom’s belly as Lux nuzzled his face against it.

The third picture showed the couple holding hands and smiling as they faced one another, and the final shot showed the group walking along the shoreline. The geotag indicated the pictures were taken in Scottsdale, Arizona, where the family lives.

Bachelor Nation Is Thrilled for the Family

On February 20, the Luyendyks shared in a YouTube video they had made a big decision together. He had a vasectomy after the twins arrived, and they decided to have it reversed.

Some people spotted decor in the background that led them to believe the video was filmed in August or September when the kids were starting school. That suggested to some fans that they were already pregnant and likely announcing soon.

On March 10, the Luyendyks shared a new video on their YouTube channel with the pregnancy announcement.

Bachelor Nation flooded the pair’s Instagram post with notes of congratulations.

Former “The Bachelor” Sean Lowe wrote, “Congrats buddy!”

Chris Harrison, the former host of the franchise, commented, “Absolutely incredible! God bless. Now time to reverse the reversal.”

“The Bachelor” alum Hannah Ann Sluss gushed, “Yay!! ❤️❤️❤️ congratulations!!! I’m so happy for you!!!”

“This is the best news! Congrats on becoming a family of six this fall! You will have the best helpers with the new 👶 🙌🙌🙌🙌 🙏🙏🙏🙏 Wishing Lauren a wonderful pregnancy,” a fan wrote.
