Naomi Campbell: Nelson Mandela has stood as a figure of strength, hope, freedom, selflessness and love, and I join everyone across the world in mourning his passing. However, he was much more than just a figurehead to me – he was my mentor, my honorary grandfather, my Tata. Since meeting him in 1993, he guided me and gave me a reason for being in the tough times of my life. He changed my perception of the world. (Facebook)
