Charlie Puth Nearly Pukes on Late-Night TV After Sipping Bird Saliva: ICYMI

Charlie Puth was feeling a little queasy when he stopped by The Late Late Show on Wednesday night (Oct. 13).

Puth showed off a silly side when he sat down to play a game of "Spill Your Guts or Fill Your Guts" with Josh Gad, Michelle Dockery and Rachel Bloom. He admitted he has a sensitive stomach, so this was definitely not in his wheelhouse. The gagging, drinking bird saliva and chowing down on a grasshopper are all proof of that.

Puth recovered enough, though, to perform his smash "Attention." It most certainly wasn't your run-of-the-mill late night TV performance, either. Instead of merely standing on stage, the 25-year-old walked around the entire set, taking pictures, strolling into the audience and enjoying a toast with James Corden before finally arriving on stage to finish up.
