LONDON -- Pop star Justin Bieber is recovering after he took a spill backstage at a concert in London on Thursday.
The Associated Press said a spokeswoman for Bieber told them the 19-year-old singer fainted and collapsed at London's O2 Arena. He was given oxygen and took a 20-minute reprieve.
Bieber's manager came onto the stage shortly after the collapse, and told the audience that Beiber was feeling "very low of breath" but he would be back out to finish the show.
The singer is scheduled for four performances at the O2 Arena. On Monday, fans criticized him for being late.
