The couple announced they were expecting another baby together in March.
Arie Luyendyk Jr., 44, and his wife Lauren Burnham, 33, have welcomed their fourth child. They announced the news on Instagram, introducing their newborn daughter, Livvy Rowe Luyendyk, born on September 18, 2025. Livvy joins her siblings 6-year-old Alessi and 4-year-old twins Senna and Lux.
Back in March, Arie Luyendyk Jr. and Lauren Burnham revealed on Instagram that they were expecting another child.
The announcement followed Arie’s disclosure that he had undergone a vasectomy reversal after the couple decided they wanted more children.
At the time, they hinted this would be their last baby, captioning their post, “Our last missing piece…coming this September👶🏼🤍.”
The next month, Arie Luyendyk Jr. and Lauren Burnham, who met on The Bachelor season 22, shared that they were having a girl through an Instagram Reel and YouTube video of their intimate gender reveal. Their kids Alessi, Senna, and Lux joined in, along with friends and family.
In a YouTube video released with the announcement, Burnham opened up about their journey, revealing they had a chemical pregnancy before conceiving this baby. She said they kept trying, but at first were unsuccessful, and when the chemical pregnancy happened, she thought it meant they were truly pregnant.
A chemical pregnancy, according to the Cleveland Clinic, is an early miscarriage that occurs before the fifth week of pregnancy.
Lauren Burnham has been candid about her pregnancy experiences on social media. In August, she posted a list of baby boy names she liked, explaining that since she likely won’t have a son in the future, she wanted to share her picks.
She added that she’d share her favorite girl names later, once meeting their new daughter. Some of the boy names she listed included Rhodes, Grey, and Coast.
Arie Luyendyk Jr. and Lauren Burnham married in January 2019, around 10 months after getting engaged during The Bachelor: After the Final Rose.
