The singer needed medical attention after experiencing breathing problems during the London performance.
Bieber's manager, Scooter Braun, went onstage to reassure the crowd that the 19-year-old was okay.
"The whole show he has been complaining," Braun told the audience, according to a WENN report. "He's backstage with the EMTs [emergency medical technicians] and the doctor. They're telling him that they want him to go and see someone and see what's going on with his lungs.
Despite the health scare, Braun assured fans that Bieber was determined to come back onstage.
"He is telling me that in five minutes he's gonna come out and finish the show," the manager continued. "He might not be jumping around as much ... We're not trying to be disrespectful ... we're truly trying to put on a show ... Just bear with us ... We're gonna do the best job to finish the show."
Soon after, the "Beauty and a Beat" singer walked back on to the stage, where he was met with cheers from the audience.
"He got oxygen from emergency personnel. He insisted on finishing the show. He is on the way to the hospital right now," Bieber's rep tells E! News.
STORY UPDATE: Justin tweets he is "getting better." See a photo of him in the hospital here.
