Justin Bieber has lived to see another day and even shared a shirtless shot from his hospital bed. Look out, Olivia Wilde. But in all seriousness, he's feeling better. Belieb a sigh of relief, Beliebers!

While the Biebs collapsed backstage during tonight's (March 7) show at the O2 Arena in London, he soldiered on and did the rest of the concert, promptly hitting the hospital afterwards.

He Instagrammed this image, showing off his tighty whiteys, writing: "Gettin better listening to Janice Joplin."

It's actually Janis, but who's keeping score?

Check out that paneled wall. It's not very hospitalian. And that crooked smile.

So cute. Get better, kiddo!
