VIDEO : Madonna Responds Prince Tribute Criticism

Madonna has responded to critics of her tribute to Prince at the Billboard Music Awards. A day after her performance of "Nothing Compares 2 U" and duet with Stevie Wonder on "Purple Rain," the pop singer took to social media Monday and posted a picture of herself in a purple boa with a flower in her teeth. She wrote that anyone who wants to do a tribute to Prince is welcome to, "whatever your age gender or skin color. If you loved him and he inspired you then show it!!! I love Prince 4 ever." She later posed a video of her dancing with a caption that indicated the criticism didn't bother her.
