I'm A Celebrity...Get Me Out Of Here! jungle contestants George Shelley, Joe Swash and Vicky Pattison appear in the third episode attempting to win the cash prize. Will their time in the jungle prepare them for the forest?

In episode four The Real Housewives of Cheshire, Dawn Ward, Lauren Simon and Tanya Bardsley take on the terrifying challenges but most terrifyingly of all, not drink Champagne for a whole night!

In the last episode, Olympians Iwan Thomas, Louise Hazel and Jamie Baulch swap the athletics track for the dog run as they push themselves to their limits and attempt to take home the gold.
