Singer Michael Bublé managed to knock out a tooth during a gig in Sydney last Friday.

Digital Spy reports that he damaged his teeth while singing the second song of the concert but did not reveal to the audience that he had had an accident.

He later revealed the injury on Instagram saying "Thankfully no one knew, but I knocked my tooth out with my microphone last night during the second song!! 

"Don't worry, I'm at the dentist getting fixed up for my final show tonight in #Sydney #australia #mbworldtour #tourlife"
