The 'Made in Chelsea' star is expected to come under fire when 'The Island with Bear Grylls' hits screens later this year as, according to the Daily Mirror newspaper, he was caught on camera shoving a knife through the reptile's neck.

The 28-year-old star's shocking actions come just a few months after Lydia Bright revealed she got a fishing hook wedged in her finger while she was competing on the show.

The 26-year-old beauty decided to get a tattoo of the object etched onto her index finger in order to cover the scar that was left behind when she ran into some trouble while shooting the reality adventure programme.

Alongside a photograph of her new inking, she wrote: "So here it is my first ever tattoo. A fish hook.

"In February, I took part in the biggest challenge of my life 'Bear Grylls The Island.' I got a nasty, extremely painful fish hook stuck in my finger that left me my proud scar.

"I got this tattoo in Bali to represent my wonderful world travels and incredible experiences (sic)"

Other stars set to compete on the show include former rugby star Thom Evans, 'Embarrassing Bodies' doctor Dawn Harper, children's television presenter Zoe Salmon, politician Karen Danczuk and comedienne Josie Long.

The stars of the show have all donated their salary for the show to Channel 4's Stand Up To Cancer campaign.

'The Island with Bear Grylls' will air this autumn.
