Pop star Justin Bieber was treated by doctors after suffering breathing problems during his concert at London's O2 Arena last night.
The 19-year-old was performing the third out of four nights at the venue.
The Canadian took a 20-minute rest before returning to the stage to finish the show.
He has since sent this message to his 35 million Twitter followers:
