Justin Bieber Passes Out, Then Posts Shirtless Pic On Instagram (PHOTO)

Justin Bieber passed out backstage after his London concert on Thursday, and naturally his first thought was to alert fans that he was doing all right -- but he did it the Bieber way.

In what's strangely becoming his signature, the 19-year-old posted a shirtless photo of himself in bed listening to music, to his Instagram account and wrote, "Gettin better listening to Janice Joplin."

Seems like Bieber didn't take actress Olivia Wilde's suggestion to heart when she tweeted last week telling him to "put your f**king shirt on."

Oh, and while it's good news Bieber is getting better, we'd just like him to know it's "Janis Joplin" that he's listening to.
