MADONNA has been attacked by a dance music DJ after she referenced the rave drug ecstasy during a performance in Miami at the weekend.
The pop-star caused the stir during a surprise appearance at the electronic music festival on Saturday in Florida.
"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," Madonna said to the cheering crowd before introducing DJ AVICII.
She then added: "I have a few questions for you – how many people in this crowd have seen Molly?"
'Molly' is known as a slang term for MDMA, the active chemical in ecstasy.
After hearing her comments, popular electronic music DJ Deadmau5 took to social networking sites to criticise the singer for promoting drug use in front of younger members of the audience.
The Canadian performer, whose real name is Joel Thomas Zimmerman said: "HAS ANYONE SEEN MOLLY???" such a great message for the young music lovers at Ultra."
The star, who performs while wearing a plastic mouse head, later added to his comments on the micro-blogging site:
Twitter: deadmau5 - @MadonnaMDNAday You're a role model to 100's of millions. You have a powerful voice,EDM could use your positive influence, not "molly" talk.
This is the second controversy for the 53-year-old singer in as many days.
Her latest video Girl Gone Bad has been slapped with an age restriction after YouTube deemed it too raunchy for under 18 year-olds.
The video features Madonna in black leather hotpants and YouTube rules say videos can be restricted if they contain ‘dramatised or implied sexual conduct’.
The video, shot in black and white, shows the twice divorced mum of four writhing and grinding with scantily dressed men, in a style similar to her Erotica days, when the video for her song Justify My Love, was banned by MTV in 1990.
The song is the second single taken from her new album, MDNA, which she has claimed is a reduction of her name but is also a reference to the active chemical in ecstasy.
MDNA, Madonna's 12th studio album which was released on March 26, has received a lukewarm reception from critics.
