Justin Bieber Faints Backstage At O2 Concert In London.

Singing sensation Justin Bieber has taken teen girls’ breath away for years. Now it seems he has lost his as well.

Bieber was rushed to a London hospital Thursday night after stopping his live show briefly and fainting backstage at the O2 Arena, a spokeswoman for the star said.

But the Biebs was feeling well enough later to post a photo of himself to Instagram — in a hospital bed, wearing headphones and a little smile, but, as seems to be his new custom, no shirt.

“Getting better,” Bieber posted on Twitter. “Thanks for everyone pulling me thru tonight. Best fans in the world. Figuring out what happened. Thanks for the love.”

A spokesman for the O2 Arena said Bieber’s Friday concert will go ahead as planned.

“Good morning everyone. As things stand Justin Bieber is still set to perform the final night of his shows at The O2 this evening,” the Arena’s posted to Twitter early Friday

Follow Ups.

The hospital stop follows days of bizarre behavior by the teenage crooner, who was photographed shirtless — with his underwear showing — after his 19th birthday party last week.

He was then spotted Wednesday night wearing a creepy black gas mask while out on the town.

He (Bieber) was also forced to apologize to fans on Monday (March 4) after a delay marred his first concert at the O2 Arena.

It then continued Thursday when Bieber abruptly stopped singing, stumbled backstage and was given oxygen. One concertgoer said many fans were gasping and crying, while others wanted Bieber back.

“I thought, ‘Give the guy a break. He just fainted. He’s not a performing horse. Let him rest a second,’” said Jazz Chappell, 20.

The pop phenom was able to return after 20 minutes and finish the show before heading to the hospital, his spokeswoman said. But the scare sent his Beliebers into a temporary panic.

As at the time of this post, Celebessence.com can confirm the song star has been discharged from the hospital and headed home.

Good luck Justin.
