This may be the best celebrity Twitter fail EVER!

Oh Sam Smith …

Ever call in sick to work then accidently 'check in' to Coppers later that night? Well Sam Smith can relate.

Sam Smith - who is currently on tour in the US - tweeted fans to tell them he was too sick to meet them after the show and a mere two hours later tweets about the "Best night EVER at a karaoke bar in Nashville!!!!!!!!!"
