CBS has unveiled the official photos for the Big Brother alumni competing on The Amazing Race Season 38, premiering on Thursday, September 25 at 9 p.m. ET. Phil Keoghan returns to host the competition, which sees 13 fan-favorite housemates embark on a European adventure with their travel companion.

For the first time ever, the Emmy-winning CBS reality series will feature a cast entirely of former 'Big Brother' houseguests, along with a loved one.

That’s right, all 13 duos competing on season 38 contain at least one “Big Brother” alum. There are even two sets of exes: season 24’s Taylor Hale and Joseph Abdin and season 26’s Tucker Des Lauriers and Rubina Bernabe.
