These celebrities are ready to get down and dirty.
Special Forces: World's Toughest Test has announced the 18 famous faces who will compete on season four of the intense Fox reality series.
The Real Housewives of New Jersey alum Teresa Giudice and daughter Gia Giudice, former Empire star Jussie Smollett, The Real Housewives of Atlanta alum Eva Marcille, Sister Wives' Kody Brown and The Valley's Brittany Cartwright are just some of the TV stars who will attempt the grueling challenges used in real-life Special Forces trainings.
Joining them will be power couple Eric Decker and Jessie James Decker, podcaster Brianna "Chickenfry" LaPaglia, Montana Boyz's Mark Estes, Olympian Shawn Johnson and husband Andrew East, model Chanel Iman, actor Ravi V. Patel, Olympian Christie Pearce Rampone, retired NBA star Nick Young and ex-NFL players Randall Cobb and Johnny Manziel.
And these new recruits will certainly be pushed to their limits.
In one first look photo released on Entertainment Weekly Aug. 6, Smollett hangs onto the side of a boat as Pearce Rampone appears exhausted and collapsed inside the raft.
In another on-set image, Johnson looks stoic with a bloody nose during one of the physically demanding exercises.
Celebrity contestants certainly don't get any special treatment on Special Forces. Just ask season three contestant Denise Richards.
"I had three weeks to train and I was in the gym every single day," The Real Housewives of Beverly Hills alum told E! News earlier this year. "My daughters were terrified. They did not want me to do it. They that I was maybe not gonna make it home."
Richards even suffered an injury to her surgically enhanced boobs.
"I jumped off a bridge, too, and that’s when I ruptured my [breast] implants off of that thing," the Drop Dead Gorgeous revealed during a January episode of the Jeff Lewis Live radio show. "I still have to get them redone. I was supposed to a month ago, but couldn’t because we were filming. So I still have to get them redone.”
