When we say "last minute" we mean support act DJ Cassette had to mount the stage and inform the assembled audience at Miami's SLS Hotel that the superstar DJ was in hospital.

As for the reason for the reported hospitalisation, that remains under wraps. TMZ, who have the exclusive on this, reports that "It's unclear right now what's wrong with Avicii. Our sources in Miami say just a couple of hours ago Avicii was fully expected to perform - so it appears the problem was sudden."

They updated the story shortly after stating that Avicii, AKA Tim Bergling, had been discharged from hospital but he's "no longer a guest at the SLS. Something weird's going on down there."

He's probably decided not to go back there considering the SLS Hotel went all out for the gig, to the point of rebranding their hotel to 'Avicii SLS'...

Avicii's last tweet was sent on March 26th.
