Madonna swaps her revealing purple leotards for swish Roberto Cavalli for the video and cover of her new single Four Minutes, a duet with Justin Timberlake. Another album, another reinvention for Madge. Her new record Hard Candy will hit the shops on 28th April. Four Minutes is the lead single from the hotly-anticipated follow-up to Confessions On A Dancefloor, which spawned a record-breaking tour seen by over 1.2 million fans around the globe. Can you believe the Queen of Pop turns 50 this year?!
