MADONNA has been on the red carpet at the Cannes Film Festival for the European premiere of her Aids film. The documentary, I Am Because We Are, highlights the plight of Malawi's estimated one million Aids orphans. The 49-year-old will be joined later by a host of A-list stars including actors Sharon Stone and Sean Penn for a fund raising event. The singer is currently in the middle of court proceedings to adopt a three-year-old Malawian boy.  Madonna wrote, produced and directed the film, which shows a stark picture of desperate poverty in Malawi. It also highlights how education can help the situation. The singer received a round of applause as she entered the cinema.  "To say that this film is a labour of love is true, but that's kind of trivial because really what it is, is a journey of a lifetime," she said.  Director Nathan Rissman told the audience that it was amazing to have someone like Madonna believe in him.  "I'm so excited to be here," he said.  Madonna will join Sharon Stone later on Thursday to raise money for Aids research charity Amfar.                  - BBC
