Justin Bieber had quite a scare yesterday when he developed breathing problems while shooting scenes on the set of CSI.

His rep confirmed to E! News that Bieber suffered an allergic reaction and needed instant treatment at nearby Providence Saint Joseph Medical Canter in Burbank, California

“He is fine,” Bieber’s rep says. “He had a mild allergic reaction while they were wrapping up last night on the set of CSI. His doctor met him at the hospital to make sure everything was OK. He was released within the hour after his doctor declared him fine. He is back on set working today. All is well.”
