The 53-year-old actress is one of eight celebrities who will take part in the second series of the reality TV show, in which Bear takes them on a 12-day survival mission in Costa Rica, according to the Daily Star.

Earlier this year it was revealed that 'Mission Survive' had been renewed for a second season, after the success of the first, which saw DJ and model Vogue Williams beat Olympic athlete Dame Kelly Holmes and ex-England rugby player Mike Tindall to be crowned Bear's Mission Survivor.

Speaking about the show, Bear said: "I'm so proud of 'Mission Survive' and all it stands for: endeavour, comradeship and overcoming fears. For me it is about understanding that sometimes we have to go through genuine adversity to come out the other side better, stronger and more empowered. It is such a privilege to get to do it once more and here begins the journey to find the next ultimate survivor!"

Despite being crowned champion, Vogue admitted the process was tough, especially when she had to drink her own urine, something she hasn't been able to live down since returning home to Ireland.

She said: "Everyone thinks I'm disgusting, even I think I'm disgusting but it was just one of those things that you had to do, it was part of being a survival person so that's why I did it.

"I was begging Bear. Every time I saw him I was like, 'Please don't make us drink our wee, it's just too obvious, don't make us do it'. But no, we were always going to drink the wee so I did try and get out of it."
