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:
getting better. thanks for everyone pulling me thru tonight. best fans in the world. figuring out what happened. thanks for the love
Earlier this week he was criticised for keeping fans waiting after coming on stage late for Monday's performance.
