Justin Bieber 'Hospitalised After Fainting At O2 Gig'

Justin Bieberwas taken to hospital last night (March 7) after allegedly collapsing backstage at London's O2 Arena.

According to The Sun, the 19-year old was performing track Beauty And A Beat when he rushed off stage, leaving many fans confused by his disappearance.

A source claimed Justin "was on the verge of tears" and could be heard saying: "My lungs hurt" as he fled the stage.

A video has since emerged of JB's manager Scooter Braun explaining to Justin's fans that he had been complaining of being "light of breath" for the duration of the show.

He told the 20,000-strong crowd: "He’s backstage with the EMTs and the doctor. They’re telling him they want him to go and see about his lungs.”

Braun then confirmed that JB would finish the gig, adding: “We’re not trying to be disrespectful. Just bear with us.”

TMZ adds that the Biebster 'fainted backstage' and had to be given oxygen in a private room.

After returning to the arena to finish his set, Justin was then taken to hospital and later posted a topless snap of himself smiling in bed on Instagram, along with the caption: "Getting better listening to Janice Joplin."

The Baby hitmaker later tweeted: "getting better. thanks for everyone pulling me thru tonight. best fans in the world. figuring out what happened. thanks for the love." (sic)

Scooter also took to Twitter to update fans on JB's condition, writing: "tough kid. proud night. once again he always finishes the show. full out. true pro. now get better and rest up! strange night but proud nt", before adding: "tough as nails."

Justin's hospital dash marks another incident during his trip to London, with the star being slammed earlier in the week for arriving two hours late for his first Believe tour show at the O2 on Monday (March 4).
