Rachel Reilly and Brendon Villegas fans will apparently be getting a third chance to see the engaged couple compete on a CBS reality show.

Reilly and Villegas are among the teams competing on The Amazing Race's twentieth edition which will air next year, according to eyewitness sightings of the racing teams.

Production of The Amazing Race's twentieth edition is believed to have begun on Saturday when airport patrons spotted Reilly and Villegas and the rest of the competition's teams being filmed by camera crews as they waited to board departing flights at Los Angeles International Airport in Los Angeles, CA and posted photos of teams on Twitter.

Assuming the sightings are accurate, The Amazing Race's twentieth edition will be Reilly and Villegas' third appearance on a CBS reality series within the last two years.

Reilly and Villegas 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 as part of this past summer's thirteenth season "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 thirteenth-season finale, where she took home the show's $500,000 grand prize after winning a 4-3 jury vote over fellow contestant Porsche Briggs.

CBS renewed The Amazing Race for a twentieth edition in June and it is scheduled to premiere in early 2012.
