Justin Bieber said via Twitter Friday he is "getting better" after falling ill during a show at London's O2 arena Thursday night.
People.com quoted Bieber's manager, Scooter Braun, as telling the audience at Thursday's concert the 19-year-old singer had been having trouble breathing all night.
"He got oxygen from emergency personnel. He insisted on finishing the show," his representative told E! News after the concert.
"He is on the way to the hospital right now."
