They’re here! Bachelor couple Arie Luyendyk Jr. and wife Lauren Luyendyk‘s (née Burnham) newborn twins — daughter Senna James and son Lux Jacob — have the most unique names with the sweetest meanings. 

“We chose Lux because we heard it when we were in Holland, and one of our friends named their son that … We just thought it was a really cool name,” Lauren, 29, explained in a YouTube video released on June 22. Arie, 39, noted they asked their pal for permission before using the moniker. As for his middle name, Jacob is in honor of the former Bachelor’s grandfather.

Their daughter was named after iconic racecar driver Ayrton Senna, and her middle name is a nod to one of Lauren’s favorite uncles, who was like a second father to her.

The reality TV couple revealed they’ve had these names picked out for over two years and discovered them while choosing a name for their oldest daughter, Alessi, who was born in May 2019. “It’s so fitting when we found out we were having twins — a boy and a girl,” Arie gushed.

Even more special, Lux’s name means “light” and Senna’s means “brightness.” Lauren said the names of their “rainbow babies” had even more significance after the “dark time” they experienced following her 2020 miscarriage.

The Bachelor Nation alum gave birth to her newborn twins on June 12. Arie and Lauren announced Lux’s name via YouTube less than a week after his birth. The parents initially held off on revealing their daughter’s name, as she had to remain in the hospital after the babies were born prematurely

The reality TV couple, who met during season 22 of The Bachelor in 2018, teased the names of their new bundles of joy during Lauren’s baby shower in April. Arie threw a “surprise” party for his wife at the time and a marquee sign reading, “Baby L & S,” was the focal point of the event. However, they publicly kept the names hush-hush until after the twins’ birth.

Arie and Lauren announced via YouTube they were expecting twins in December 2020 following the couple suffering a devastating miscarriage earlier that year. 

“It’s hard to know what to say right now,” Lauren captioned a photo of her, Arie and their daughter, Alessi, who was wearing a “big sister” tee. “I’ve been crying on and off for the past 3 months … right now is no different. So so grateful.” She also included a rainbow emoji to honor the child they lost.

One month later, they revealed the sex of the twins, a boy and a girl, during an adorable gender reveal with blue and pink cotton candy. 

“Alessi is getting a baby BROTHER [and] a baby SISTER,” the Virginia Beach native gushed via Instagram while sharing snapshots taken by talented photographer Jennifer Griffith of Griffith Imaging. “We couldn’t be more excited!” For his part, Arie added, “BOY! GIRL! How did we get so lucky @laurenluyendyk?! So excited to meet the @luyendyktwins.”

The race car driver and Shades of Rose designer are amazing at choosing unique names for their little ones. They previously explained they created Alessi’s moniker on their own.

“It was a name we kind of tweaked into something unique,” Lauren told Entertainment Tonight before giving birth to baby No. 1. “We don’t really know anybody who’s named that.”

Congrats to the new family of five!
