Madonna has started her “Sticky and Sweet Tour” to promote her new album, “Hard Candy.” These pictures showed her on stage in Cardiff, Wales, on August 23. The main theme of her stage wardrobe would be sexy lingerie. At 50, Madonna remains as one of the most beautiful women in the world. She can easily give Rihanna a run for her money. RiRi loves to wear corsets in her shows too. Who do you think has more spice in their shows? Madonna or Rihanna?
