If you are in any way squeamish about insects or have a general phobia about things crawling into your body while you sleep (and who doesn't), brace yourself for pure nightmare fuel.

Charlie Hunnam joined Rupert Friend and Demi Lovato on 'The Late Late Show with James Corden' last night and between talking about combat skills and Hollywood, Hunnam shared a horror story from shooting on location in South America that literally scarred him for life.

The worst part? It didn't even happen in the wilds of Columbia but back in his hotel room.

So the moral of this story is never leave the country or sleep ever again without earplugs and a heavy coating of DEET.
