WINNER: Carine Felizardo was overcome with joy at winning Miss Bumbum.

A shapely blonde model from northern Brazil has won a different kind of beauty pageant.

Carine Felizardo, 25, has been crowned this year’s Miss Bumbum — Portuguese slang for buttocks.

A 10-person jury decided Felizardo had Brazil’s best-shaped and sexiest derriere.

Wearing a skimpy white string bikini and a golden sash with ‘‘Miss Bumbum 2012’’ in green letters, Felizardo told the audience: ‘‘Working out at the gym for 10 years has paid off.’’

‘‘I feel fully realised. I really did not expect to win. It is a dream come true,’’ she said.

Felizardo was one of 15 finalists chosen through online voting among 27 contestants representing each of Brazil’s states.
