The most treacherous show on reality TV is back with a whole new cohort.

"The Traitors" revealed its Season 4 cast on June 13, according to a press release from Peacock. The lineup includes up stars from franchises like "Big Brother," "Love Island" and "The Real Housewives," as well as a certain celebrity football mom.

The Emmy-winning series will see the return of "Real Housewives of New York City" favorite Dorinda Medley, who was the first person eliminated from the game last season.

Fans of "Survivor" can look forward to seeing Season 29 winner Natalie Anderson, Season 44 winner Yam Yam Arocho and beloved podcast host Rob Cesternino. Meanwhile, "RuPaul's Drag Race" fans will be rooting for Season 10 icon Monét X Change to take it all.

In line with the trend of having a celebrity relative on the cast − last season saw Zac Efron's brother Dylan Efron become one of its winners − the newest season will include Donna Kelce, the mother of Kansas City Chiefs tight end Travis Kelce and former Philadelphia Eagles center Jason Kelce.

Scottish actor Alan Cumming will also be returning to host Season 4, Peacock confirmed. The release date for the season hasn't been announced.

Viewers will have to wait for the season premiere before learning which contestants will be Faithfuls and which will be Traitors. And just like Season 2 and 3, there's a possibility more reality stars will be revealed later on.
