Rachel Reilly and Brendon Villegas have announced they are expecting their first child.

The Big Brother and The Amazing Race couple joined Julie Chen for an interview about Big Brother's Season 17 competition during Wednesday night's broadcast, and after discussing certain players and strategies, they made a big announcement.

"I always say no one comes in between me and my man," Reilly said, "except a Brenchel baby!"

Villegas smiled as Reilly bounced up and down in excitement.

The couple first met when they competed on Big Brother's twelfth season in 2010. After beginning a "showmance" during the competition, Reilly and Villegas continued dating and got engaged on Valentine's Day before returning to Big Brother in 2011 as part of the thirteenth season's "duos" twist in which three pairs of former houseguests were given a second chance to compete on the show.

While Villegas was evicted -- twice -- from the Big Brother house midway through the competition, Reilly made it to the Season 13 finale, where she took home the show's $500,000 grand prize after winning a 4-3 jury vote over fellow contestant Porsche Briggs.

The couple then made their third appearance on a CBS reality series when they competed on The Amazing Race's twentieth edition in early 2012. They finished the season's final leg in third place.

After their Amazing Race stint, Reilly and Villegas got married on television atop the AT&T Center, a 32-story high-rise in downtown Los Angeles, in September 2012. Reilly arrived at the wedding at sunset via helicopter because "she wanted to arrive like a big celebrity," David Tutera, celebrity wedding planner and host of My Fair Wedding, told People at the time.

The bride wore an ensemble that was "not at all a bridal gown," according to Tutera, as Reilly reportedly walked down the aisle in a floor-length, silver-sequined Missoni dress which featured a sweetheart neckline.

Reilly and Villegas decided to compete on The Amazing Race again for its third All-Stars edition in early 2014. The couple finished in third place again but broke a record by becoming the first team to ever complete the show's entire race course twice.
