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.

As “The Amazing Race” returns this fall with a group of all-star “Big Brother” alums competing against each other - and paired with a friend or family member as their travel partner - CBS has released the names of those teams racing around the world for Season 38.
