A 25-year-old model with a 42-inch bottom has been crowned Brazil's new Miss Bum Bum.

Dai Macedo, who represented the central state of Goias in the nationwide search for the woman with the most bodacious butt in all of Brazil, was chosen from among 15 finalists by the contest's grand jury in Sao Paolo this week.

"It's a lot of work, a lot of devotion," Macedo told Agence France-Presse by way of an interpreter. "I denied myself a lot of things. No nightclubs. No sweets. I went to the gym Saturdays and Sundays."

The sacrifice is well worth it. Miss Bum Bum winners become instant celebrities in Brazil, and receive a fortune in endorsements.

But the glamor comes with its share of drama. Earlier this year, a columnist for Brazilian newspaper O Dia accused Miss Bum Bum contestants Mari Sousa and Eliana Amaral of bribing judges in attempts to win.
