The Big Brother alums, who welcomed their first child last week, are revealing her name and first photo exclusively to PEOPLE.
Adora Borealis Villegas was born April 8 at the UCLA BirthPlace Westwood at Ronald Reagan UCLA Medical Center in Los Angeles, weighing in at 6 lbs., 10 oz. and 19.5 inches long.
“She’s our perfect little angel!” the proud new parents tell PEOPLE.
As for their unique name choice?
“We came up with the name Adora because we adore her, she’s ‘Adora-ble,’ and we wanted a Spanish name to celebrate her Hispanic heritage,” the couple says. “Borealis was Rachel’s must-have middle name because she’s always been infatuated with the natural beauty of the Aurora Borealis, the Northern Lights. Of course Brendon loves the name because he is a physicist and science nerd! We love the name because Adora lights up our lives like the Borealis lights up the night sky.”
The couple first met in 2010 on the show’s twelfth season, before returning to the house for a second time the following year, when Reilly won. They later appeared as a couple on two seasons of The Amazing Race.
Villegas, 35, and Reilly, 30, said “I Do” in September 2012 atop the AT&T Center in downtown Los Angeles.
