Justin Bieber passed out on stage tonight in London, but is feeling better and just Tweeted a special shout-out to his fans for their help and support.
As usual, he called Bieliebers the best fans in the world.
With four songs remaining in his show, JB began to feel weak and was pulled backstage and attended to by emergency personnel for 10 minutes.
Bieber's manager explained that Justin would return to finish the show, which he did (see Scooter Braun address the audience in the clip below).
It's still not clear what exactly caused the 19-year-old singer's scary collapse.
According to Braun and Bieber's own Tweet, he is on the mend but doctors will continue to evaluate him and try to figure out what happened out there.
Maybe a combination of stress and exhaustion?
Who knows, but a little rest and relaxation can only help going forward. We wish the Bieb, who's battled through a lot of adversity lately, a speedy recovery.
