Brazil's 'derriere extraordinaire', Dai Macedo has won the Miss Bum Bum contest in Sao Paulo Political correctness takes a back seat as Dai Mecedo takes home best bum in Brazil honours. Courtesy MissBumbumBrazil/YouTube POLITICAL correctness has taken a back seat as Brazil's business hub of Sao Paulo played host to a contest honoring women's rear ends. Namely, the 2013 edition of Miss Bum Bum - in which 15 young women competed for the right to be crowned as the owner of the most delightful derriere. The winner, who got the vote of a half-male, half-female jury, was 25-year-old Dai Macedo from the central state of Goias for her 107 centimetres (42 inches) of 'bumbum.' Second was Eliana Amaral from Pernambuco in the north and, bringing up the rear, so to speak, was third-placed Jessica Amaral from the central northern region of Para. Dai Macedo, 25, has been declared the winner of Brazil's Miss Bum Bum contest. Administration student Ms Macedo had been embroiled in controversy leading up the event, taking to social media to suggest the result would be fixed to give the title to rival Mari Sousa. Ms Sousa, 25, and Eliana Amaral, 24, were also the subjects of media allegations they may have bribed judges to back their respective campaigns. There was also a report in daily O Dia of further skullduggery amid suggestions an Xray showing Ms Amaral's assets to be implant free was a forgery.

In recent days the Twitter sphere has been awash with catty remarks from some contestants denigrating each other - the dreaded word cellulite proving a favored insult - and the voting process. "I'm all emotional - I didn't expect to win," gushed Ms Macedo as she put the pre-event controversy behind her. All hell broke loose on social media sites but now I can say the contest was real. Eliana Amaral from Pernambuco was runner up in the Miss Bum Bum contest. The new Miss Bum Bum indicated her backside had not always been such a marketable asset. It isn't 100 per cent natural - I had a butt lift. I always had a large backside but liposuction improved it," she admitted. Indicating a desire for further fame and fortune the brunette said she hoped one day to become a television presenter.
