'Miss Granny Bum Bum' - a new section of the annual Miss Bum Bum competition - was introduced at this year’s event in Sao Paulo, on Wednesday evening.Contestants aged 50 or over strutted down the catwalk at the La Fiesta club in front of judges and an audience. One contestant, Silvia Kubula, captured the light-hearted spirit of the event: "I think it was worth it, as everything I do nowadays is fun. I have done so many things during my lifetime that nowadays everything that comes is welcome."
