Charlie Hunnam [1] and Demi Lovato [2] are beautiful, yes, but they're also tough. On Wednesday, both stars appeared on The Late Late Show With James Corden [3], where they dished on their ju-jitsu skills and Charlie told a horrific story about an encounter he had with a bug while filming The Lost City of Z in Colombia. The actor revealed that one night in his hotel room, he woke up with a little creature stuck in his ear canal that ended up biting off a large chunk of his eardrum (pause for vomiting). The group then watched a video of Demi taking down her boyfriend [4], MMA fighter Guilherme Vasconcelos, and Charlie admired her skills. Watch both videos here, then check out Demi and James's Divas Riff-Off [5].
