Madonna has defended herself amid growing criticism surrounding her tribute to Prince at Sunday night's Billboard Music Awards. The ?Material Girl? singer began her performance to her former flame, who died last month, with a touching rendition of his Nothing Compares 2 U, which became a huge global hit for Sinead O?Connor. Madonna, wearing a lavender suit and ruffled shirt like the ones Prince often performed in, was then joined by Stevie Wonder for a take on the tragic star?s Purple Rain anthem. Critics were quick to take a swipe at the performer's performance, so Madonna took to Instagram to defend herself. ?Anyone who wants to do a tribute to Prince is welcome to,? she wrote alongside a snap of herself in a patterned purple ensemble. ?Whatever your age Gender or skin Color. If you loved him and he inspired you then show it!!!! I love Prince 4 ever.?
