Volatile supermodel Naomi Campbell will soon adorn a special charity stamp in Austria, created to raise funds for SIR Elton John's AIDS charities. The London-born beauty is set to host the Rocket Man's annual Vienna Life Ball on 20 May (06), and she is always keen to lend her support to fighting the deadly disease. A spokesperson says, "Naomi is a keen supporter of AIDS causes and saw Nelson Mandela in Africa earlier this month (APR06). "She'll be hosting the Life Ball, which is a gorgeous event at Vienna's city hall and has featured designs by Vivienne Westwood and John Galliano."
