The 2017 Miss BumBum hit the streets of Sao Paulo, Brazil this week.

Striding down the streets of Sao Paulo in their black swimsuits, these glamorous models have been stopping the traffic as they promote the much anticipated Miss Bum Brazil competition.  What really matters is the 27 hopefuls kicked off the competition by showing off their (potentially) award-winning asses, all in unison. This year there's an amputee in the running, and based on these pics she's got a good shot at the prize.

Brazilian model Rubia Machado (L), representative of the state of Tocantins and who had her leg amputated after being run over by an ex-boyfriend years ago...it's Brazil these kinds of things happen every day.

Miss Bum Bum first started seven years ago and developed into a major glamour model competition in Brazil. Several spin-offs have been held as well as the world famous annual competition in Brazil. 

In a country obsessed with the female backside, winners of the hotly-disputed contest become overnight celebrities and often go on to earn millions in modeling contracts and endorsements.
