The tough reality show returns for a brand new series on 3 March, as a new group of stars take on Bear's 12-day survival expedition in South Africa.
Bear said: "This is one of the toughest shows I have ever done - there was no let up for the celebrities from the get-go, having to work together and dig deeper than they might ever have imagined. But that's the reality that genuine survivors face: dig deep or die."
This year we've been promised "more terrifying challenges" than ever before, including surviving dangerous animals, high-octane survival scenarios, and ever changing weather conditions from harsh, hot sun to torrential rain and bitterly cold nights.
Eek. Sounds brutal.
Oh, and on top of all that they'll have to contend with hunger, sleep deprivation and absolutely no home comforts or luxuries.
"The celebrities might be used to performing - whether it's on stage, TV or in a sporting arena, but the wild is the ultimate leveller and out in the mountains there was little room for egos," said Bear.
"They had to work hard and face their fears every day, and for some of them it was just too hard both physically, mentally and emotionally. By the last episode we were down to just three, all hugely capable individuals, but at the end I chose one incredible Mission Survivor as the person that I believe shone the brightest."
At the end of each episode (there are six in total), one celebrity is sent home, before Bear crowns his ultimate Mission Survivor, who must have the characteristics of positivity, resourcefulness, courage and determination.
The full list of celebrity competitors is:
- Waterloo Road and Casualty actress Chelsee Healey
- Les Miserables actress Samantha Barks
- Coronation Street actress Michelle Collins
- Dancing On Ice judge Jason Gardiner
- Ex-footballer and coach Stuart Pearce
- Actor Neil Morrissey
- Arsenal and England Ladies' footballer Alex Scott
Bear Grylls: Mission Survive starts 3 March at 9pm on ITV.
