Gareth Gates says the final interrogation on 'Celebrity SAS: Who Dares Wins' was the "worst experience" of his life.

The 39-year-old singer makes up one fifth of the five celebrity recruits remaining in the Channel 4 series, alongside former Health Secretary Matt Hancock, ex-'Love Island' star Teddy Soares, model Danielle Lloyd, and former Olympian Perri Shakes-Drayton.
In Sunday's (05.11.23) finale, the quintet are subjected to punishing interrogation techniques, as they use a cover story to hide their true mission, over 14 hours, and Gareth admitted it was "torture".
He said: "It was definitely the worst experience of my life.
"I haven't ever felt pain like it. When you are held in those stress positions for hours, it’s torture.
"I've seen the show and I've watched it on the screen but you just aren't able to understand the pain of holding those positions, which look so simple.
"Also, these noises that they put in your ears, you become extremely anxious.
"It isn't just the coupling of the physical pain of the stress positions with the anxiousness. The sounds make you feel awful, it really is unbearable. It was really horrendous."
Perri also described the interrogation, at the hands of an elite Hunter Force deep in the Vietnamese jungle, as "torture", and Matt said it was "very unpleasant".
The former 'I'm A Celebrity... Get Me Out Of Here!' star said: "It was really one of the most difficult things I've ever done and a very unpleasant experience.
"The only way through it was to have the same attitude that I had during the whole course, to just keep sticking around for a few more minutes all the way through, even when the interrogators were trying to rile me."
Danielle admitted it was "intense", and she was physically and mentally exhausted throughout.
She said: "This was intense. The noises just literally f*** your head up.
"I'd not eaten, I was wet, it was cold. It was just so hard to try and stay awake and try and stay focused.
"You're exhausted physically and you're exhausted mentally as well."
The 'Celebrity SAS: Who Dares Wins' finale airs on Sunday 5 November at 9pm. Viewers can stream or watch live on Channel 4.
