Pop star Justin Bieber
Pop star Justin Bieber has been released from hospital and given the green light to resume his tour after suffering breathing problems on stage.
The 19-year-old singer took a 20-minute break during Thursday's show at the O2 arena in London as his manager told the crowd he was "light of breath".
He later had a check-up in hospital but is expected to perform on Friday, reports the BBC.
A spokesman said: "While he's feeling a little under the weather, he's planning on going ahead with tonight's show."
Friday's show will be the final concert of a four-night run at the O2 arena.
After Thursday's show, the heartthrob wrote on Twitter that he was "getting better. thanks for everyone pulling me thru tonight. best fans in the world. figuring out what happened. thanks for the love".
He also sent a picture of himself, via Instagram, lying in what appeared to be a hospital bed with the caption "gettin' better".
His spokeswoman Melissa Victor said: "He fainted and took a 20-minute reprieve and was given oxygen."
In a video posted by a fan on YouTube, Bieber's manager Scooter Braun was seen on stage explaining why the show had come to a temporary halt.
He told fans: "Justin got very light of breath, the whole show he's been complaining. He's backstage with the EMTs [emergency medical technicians] and the doctor.
"They're telling him they want him to go and see somebody and find out what's going on with his lungs, he's just told me that in five minutes, if it's OK with you guys, he's going to come out and finish the show.
"So he might not be jumping around as much and everything else, 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."
Bieber did return to complete the show before being examined by medical staff.
The singer has had a whirlwind fortnight in the UK, being photographed in several nightclubs, in between his concerts in Manchester, Liverpool, Birmingham, Nottingham and London.
He was criticised for keeping fans waiting after coming on stage late for Monday's performance in London.
He will move on to Portugal and Spain next week and has 63 live dates remaining on his world tour, which lasts until August.
Bieber made headlines on the very first show in Glendale, Arizona, last September when he was seen vomiting on stage but managed to finish the concert.
