Justin Bieber Cleared To Perform After Concert Collapse

After collapsing on stage
 during his concert at London's O2 Arena on Thursday night, Justin Bieber is expected to suit up for his fourth and final show at the venue on Friday (March 8).

An early morning tweet from the O2 read, "As things stand Justin Bieber is still set to perform the final night of his shows at the O2 this evening."

Bieber left the stage
 near the end of his show on Thursday night for about 20 minutes to receive oxygen after collapsing during "Beauty and a Beat." He was treated backstage by an EMT, recovered enough to finish his final four songs and then went to a local hospital for further observation.

Bieber slams "rumors, rumors and more rumors" about his crazy week in London.

He later tweeted that he was "getting better" and "figuring out what happened, thanking his fans for helping him pull through the episode. He posted a shirtless Instagram pic overnight in which he's seen laying in a hospital bed with headphones on with the message, "gettin' better listening to Janice Joplin."

The health scare capped what's been a challenging 19th-birthday week for Bieber. First, he left a London nightclub in a huff after allegations from "dummies"
 that he tried to sneak an underage Jaden Smith in, then he got booed by fans for showing up nearly an hour late
 for his Monday night gig at the O2.
