Rear of the year: Dai Macedo won Miss Bum Bum 2013 with her 42in bottom (
Eliana
Amaral, from Pernambuco in north Brazil, was awarded second place while
bringing up the rear was Jessica Amaral from the central northern
region of Para who came third.
Ms
Macedo, an administration student, had been embroiled in controversy
leading up the event when she suggested on social media that the result
would be fixed to give the title to rival Mari Sousa.
The
contest was plunged into further chaos when rivals accused Ms Sousa,
25, and Ms Amaral, 24, of paying thousands of pounds to the event's
judging panel for the right to come first and second.
Brazil's
O Dia newspaper reported that Ms Amaral, a law student representing the
northeastern state of Pernambuco, had allegedly paid organisers around
£18,000 for second place

The
O Dia newspaper also alleged that Ms Amaral's impressive derriere is
not entirely natural - which would eliminate her from the competition -
and that an X-ray she says proves she has no implants in her bottom is
fake.
Contestants took to Twitter to insult each other in the lead up to the competition.
Speaking after her win, Ms Macedo said: 'I'm all emotional. I didn't expect to win.
'All hell broke loose on social media sites but now I can say the contest was real.'

The new Miss Bumbum 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 said.
The brunette said she hoped one day to become a television presenter.
Macedo also won 5,000 reais ($2,100) and will also net ten times that in advertising contracts.
The
Miss Bumbum contest begins with 27 candidates chosen to represent each
of Brazil's 26 states and the federal district Brasilia.
The
women are then whittled down to a final 15 in an online eliminatory
round, before a winner is chosen by a judging panel of six women and
five men.
Second
place has also become a coveted position after previous years' runners
up have achieve greater fame than the actual winners.
