Pharrell Williams has described his new tunes with pop tart Madonna as "hot", with the pair even roping Kanye West into proceedings.

The producer has been recording Madonna's new album, and Kanye apparently laid down a rap for them after finding himself in the same LA recordings studio due to his own superstar collaboration with Michael Jackson.

Speaking from the launch of his new shop in New York this week, Pharrell said, "It was crazy. I don't want to say too much. I'd rather wait for you to hear it. It's awesome though. It makes the speakers bleed. It's hot!"
