Justin Bieber is recovering after fainting backstage at a concert in London.

A spokeswoman for Bieber told The Associated Press late Thursday that the 19-year-old pop star was given oxygen and took a 20-minute reprieve after fainting backstage at London’s O2 Arena.

In a video of the concert posted online, Bieber’s manager appeared on stage Thursday and told the crowd that the singer was feeling “very low of breath” but would return to finish the show.

The “Baby” singer is in London to perform four concerts at the O2 arena. He was widely criticized for arriving late to his first show Monday.
