Superstar Madonna has been reportedly accused of using a disco sample without permission on her hit new album CONFESSIONS ON A DANCE FLOOR.

Composer DOMINIC KING tells Britain's The Sun newspaper the MATERIAL GIRL allegedly used his disco riff on her album track GET TOGETHER.

King claims he originally lifted the riff from Chaka Khan's track FATE - with permission - and used it for the hit dance anthem MUSIC SOUNDS BETTER WITH YOU, performed by STARDUST.

King says, "I know her song uses my riff and I'm surprised myself and co-writer FRANK MUSKER didn't get a call.

"It would have been nice to have been asked.

"I am almost certain a discussion about money will happen with her people. These things can be settled in retrospect and something will definitely be happening, believe me."
