Former London art dealer Barnes Thomas, 29, appeared as a contestant on Bear Grylls ' survival skills show 'The Island' in 2018 before setting up as a farmer in Cornwall.
While Bear picked up many skills as an SAS trooper, his love of adventure came from the start, with early snaps showing the star throwing himself into the action.
The adventurer, 50, took to Instagram on Wednesday to share a heartfelt snap of his wife Shara, marking their 25 years of marriage - just ahead of his new Netflix show, Celebrity Bear Hunt.
