Big Brother stars Rachel Reilly and Brendon Villegas have welcomed their first son, Adler Mateo, who will now be a young brother to four-year-old Adora Borealis. Rachel and Brendon were introduced to the fans on Big Brother 12. At the time, Rachel was a 25-year-old cocktail waitress from Las Vegas, Nevada. In turn, Brendon was a 30-year-old high school swim coach from Riverside, California. Rachel was always aloof, charismatic, loud, and unapologetically girly. Brendon, a lover of science, was much more serious, disciplined, and contained. This was a very unlikely duo to end up dating each other, but as fate would have it, BB12 brought them together.

The following year, the Big Brother 13 players had to compete in pairs for a good stretch of the season. To honor that tradition and celebrate all the iconic pairs that have competed on the show, producers brought back three very high-profile pairs: Evel Dick and Daniele Donato from BB8, Jordan Lloyd and Jeff Schroeder from BB11, and Rachel Reilly and Brendon Villegas from BB12. That year, most of the vets were taken out pretty early. Only Rachel and Jordan were able to last in the house, and Rachel went on to win the season. Over the years, Rachel has become a very prominent figure within the Big Brother franchise.

On April 8, 2016, Rachel Reilly and Brendon Villegas welcomed their first-ever child, Adora Borealis Villegas, who is now four years old. In 2020, Rachel announced that she was pregnant with their second child. In fact, it was precisely this pregnancy that blocked Rachel from being cast on Big Brother 22: All-Stars. Nonetheless, they are very happy to now welcome their second kid - and first son - together. Per Us Weekly, the baby boy is called Adler Mateo Villegas. The publication also reported that this was a "super hard and scary" labor for Rachel. She told the magazine, "At one point I was on oxygen and it lasted longer than my birth with Adora. Almost 15 hours he did not want to come out of the womb."

Thankfully, tough labor aside, Big Brother 13 winner Rachel is now having a good time taking care of her baby boy at home. It's clear that Adler is healthy, adorable, and very loved by his parents and big sister. Now that she kept up with this latest All-Stars season and has given birth to two children, Rachel would be a wonderful addition to a future installment of Big Brother. The fan can definitely keep hoping for that to happen.

The Big Brother fans are wishing a lot of happiness and good health for Adler and his family. Only time will tell if his personality will turn out to be more like Rachel or more like Brendon.
