POP superstar Justin Bieber is planning to push on with his next UK show despite a health scare which saw him leave the stage mid-song and still continuing to feel “under the weather”.

The Canadian teenager – playing sell-out shows at London’s O2 Arena – posted a picture of himself online lying in a hospital bed shortly after the show, during which he had to take a break as he struggled to breathe.

In a message to fans, he said he was “getting better” and trying to figure out what happened as his eventful UK tour took another colourful twist with the latest drama.

It came in the week in which he upset thousands of fans by starting his first of four nights at London’s O2 arena so late that many had to miss most of the show.

Some of his young devotees were in tears as they left to catch transport home.

Last night, 19-year-old Bieber was midway through performing the track Beauty And The Beat when he walked off.

His manager, Scooter Braun, told the audience that the singer was seen by a doctor backstage at the venue, who told him not to return to the stage.

Braun told the 20,000 crowd: “Justin got very light of breath, the whole show he’s been complaining. He’s backstage with the EMTs (emergency medical team) and the doctor.”

He went on: “You guys need to be patient with us, we’re not trying to be disrespectful, we’re not trying to get you guys home late, we’re truly trying to put on a show for the people who love him.”

However, he did resume his performance.
