The Bachelor couple Arie Luyendyk Jr. and Lauren Burnham have revealed the gender of their fourth child together.
Arie, 43, and Lauren, 33, took to Instagram and posted a joint gender reveal video on Wednesday, April 16 that also featured their three children -- daughter Alessi, 5, and three-year-old twins Lux and Senna.
In the video, Arie and Lauren popped two giant black balloons that exploded with pink confetti inside.
The Bachelor couple therefore learned that Lauren is pregnant with a baby girl.
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.
Arie and Lauren announced that they're expecting their fourth child together in March after Arie reversed his vasectomy.
"Our last missing piece," Lauren captioned a carousel of pictures of her immediate family at the beach.
"Coming this September," she added, tagging Arie in her post.
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 last summer, he didn't open up about his vasectomy until February 2025.
Lauren shared how she and Arie had been trying to get pregnant for a while but she experienced a chemical pregnancy.
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 had made it clear in a video that he was done having kids, and then he had a vasectomy done 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.
