The reality television alums are expecting a baby boy, the couple reveals exclusively to PEOPLE. The pair — who welcomed their daughter Adora Borealis, 4, in April 2016— is "so excited" to bring a baby boy into the family, Reilly tells PEOPLE. "It's going to be so fun to have a girl and a boy! Adora is going to teach her baby brother so much and I can't wait to meet him!" Reilly says, admitting that she "totally wanted a baby boy." While the couple hoped for a son in their future, Villegas says the most important thing is that everyone is healthy. "Of course we both wanted a boy, but when you become pregnant immediately before the onset of a major pandemic, all you can focus on is keeping your family safe," he tells PEOPLE.

"I imagine having a boy will be different in all the ways we traditionally imagine, e.g. getting peed on while changing a diaper," Villegas teases. Even more, their son will be the "first to carry the family surname." When Reilly broke the news, Villegas says he was "besides [himself]." However, Reilly adds that her sex reveal to Villegas didn't go as planned. "I made him and Adora cupcakes and I wanted the inside to be blue but I didn't have blue icing or chocolate or anything," she says. "I had green chocolate so I put the chips in the center!" "Brendon took a bite and said they were good, and I asked if he liked the inside — he was not getting it!" she remembers. "I finally said to him to open the cupcakes and he said 'Oh cool.' I was like, 'They are green,' and he finally got it!"

The couple first met in 2010 on season 12 of Big Brother, before returning to the house for a second time the following year, when Reilly won.
