Madonna makes drug reference at Miami Festival?

Madonna appeared to make a drugs reference during a surprise appearance at the Miami Ultra Music Festival last night (24 March, 2012).

The pop Queen took to the stage joining DJ Avicii behind the DJ booth to spin his remix of her new single 'Girl Gone Wild'.

The 'MDNA' star seemed to make a drug reference, asking the audience if they had ever seen 'Molly'. Molly is another term for MDMA or ecstasy, and is the basis for Madonna's pun-based new album title.

She was also photographed backstage with Avicii, David Guetta and Xavier de Rosnay of French dance duo, Justice.

"I've been here many years in spirit but it's good to finally be here standing on the stage, looking at all you people who have come here from all around the world, I see flags from everywhere," she said as she introduced Avicii. "In my world, the words music and dance are not separated, electronic music has been a part of my life since the beginning of my career and I can honestly say, that a DJ saved my life.

“How many people in this crowd have seen Molly? Are you ready to dance? Are you ready to sweat? Are you ready to make some noise? Are you ready for the next DJ motherf***ers?"
