Also participating are journalist and author Alexandra Pascalidou and comedian and program leader Ahmed Berhan.
New this year is that the participants have been able to apply to the program themselves.
"This season, we will see a psychological dilemma that we have not seen before. Backstabbing gets a whole new meaning, and betrayal occurs on a whole new level," says game leader and program leader Dragomir Mrsic in a press release.
"The Traitors" is described as a psychological game. It's about the participants trying to figure out who in the competing group are traitors and who are "loyal".
This year's season premieres on October 28 on TV4 and on Tv4 Play.
