Avicii cancelled his show at Hyde Beach in Miami less than hour before he was due on-stage on Thursday (March 27, 2014). DJ Cassette told the crowd at the SLS Hotel in Miami Beach that Avicii had been admitted to hospital.

Sources tell TMZ.com that the problem was sudden and that Avicii was fully expected to perform his set. It remains unclear what was wrong with the DJ and he was discharged a couple of hours later. Insiders he is no longer a guest at the SLS Hotel, which led the celebrity gossip site to suggest, "Something weird's going on down there."

Avicii's SLS gig was a warm up for this weekend's Ultra Music Festival. The incident appears stranger given the SLS boutique hotel had renamed itself after the DJ for the duration of the festival.

Most recently, Avicii revealed that he was working with Madonna. In a post on her Twitter account - accompanied by an Instragram photo - Madonna revealed, "The End of a long week with Viking Leader AKA DJ Virgo AKA Avicii! So many great songs! #icantwait #revolution (sic)'

She made another post which showed her playing the guitar with Avicii and a group of people - adding, "Viking Harem! Great Music Great Vibes! We were grinding on that. Wood! #rebelheart (sic)"

As well as his own album True, Avicii has worked with numerous artists including Leona Lewis, David Guetta, Aloe Blacc, Adam Lambert and Nile Rodgers.
