Rachel Reilly and Brendan Villegas met when they competed on Big Brother's twelfth season in 2010.

They continued dating after the show and got engaged on Valentine's Day before returning to Big Brother in 2011 as part of the thirteenth season's "duos" twist. Rachel won the $500,000 grand prize that season.

The couple then competed on Season 20 of The Amazing Race in 2012, followed by The Amazing Race's third all-stars edition in 2014. The team finished both seasons of The Race in third place.

Rachel also competed on The Amazing Race for a third time with her sister Elissa Slater on Season 31 in 2019.

Rachel and Brendon got married in September 2012 and announced they were expecting their first child together in September 2015.

The couple welcomed their baby girl, Adora Borealis, in April 2016.

In May 2020, Rachel and Brendon announced they were expecting their second child together.

"OH Baby!!! WELCOME BRENCHEL BABY #2! Happy Mother's Day! We have a lot to celebrate this year. As a mom it's my day to celebrate Adora & OMG baby #2!!" Rachel captioned an Instagram posting in which they celebrated the new pregnancy with white and yellow balloons outdoors.

In the photo, Rachel was gently cupping her noticeable baby bump in a floral-print dress.

"I can't believe I'm pregnant! We've been trying for a while to have another... Did you know that the 2-3 days before ovulation are when you have the best chance of getting pregnant ladies?! That's a short window!!" Rachel continued.

She added, "I can't wait for what this pregnancy has in store for us!!!!"

Rachel gave birth to the couple's second child, a baby boy, in November 2020.

"Thank you for all the well wishes for Rachel and the baby. Rachel and our baby boy are both healthy and doing well. They are recovering at UCLA," Brendon tweeted.

"I am sure it will not be too long until Rachel shares some pics, but I will leave that up to our momma warrior. No name as of yet!"

The couple later revealed they had named the baby Alder.

"Welcome little baby boy Adler!!!!" Rachel wrote on Instagram.

"Our family of 3 has become a happy family of 4!!!!! We couldn't be more excited. This guy has filled our hearts and home with so much joy. Thankful for my hubby @brendonvbb12 who is the best partner and such a strong rock in our family!!!"
