Appearing on I’m A Celebrity… Get Me Out Of Here! is no mean feat – celeb contestants who are used to living in the lap of luxury are pushed to their limits by the basic conditions, lack of food and, of course, the gruelling Bushtucker Trials. It’s no surprise then, that all campmates have to undergo medicals to make sure they’re healthy enough to participate. However, over the years we’ve seen a number of campmates who are old enough to be collecting their pensions. Whilst the older campmates are often excluded from many of the trials ‘for medical reasons’, their fascinating life stories mean they can still become some of the show’s most popular contestants.Last year, we saw the oldest ever winner of I’m A Celeb, as 71-year-old football manager Harry Redknapp was crowned King of the Jungle, triumphing over young whippersnappers like Emily Atack and James McVey. The 2018 series also saw 69-year-old presenting legend Noel Edmonds taking to the jungle. One year before that, in 2017, Stanley Johnson became by far I’m A Celeb’s oldest ever contestant as he was 77 years old at the time of his appearance. Despite his age, politician and author Stanley, who is the father of the UK’s current Prime Minister, Boris Johnson, managed 18 days in the jungle before being voted out by the public. Meanwhile, the oldest ever female campmate to appear on the show was actress Stefanie Powers, who was 69 years old when she competed in the eleventh series of I’m A Celeb back in 2011. If the rumours are true, she’s about to have this record taken away from her by 70-year-old Caitlyn Jenner, who’s said to be heading to the jungle this year.Take a look at the video above for the full ranking of the oldest ever I’m A Celeb campmates!
