THE annual Miss Bum Bum competition kicks off this weekend – with several voluptuous babes battling it out for the top prize.

drThis year’s competition looks set to be the biggest yet, as dozens of wannabe winners roll up to do battle for the title.

ddBut he 2017 edition of the contest features a load of sweeping changes to the rules.

Bums bigger than 107cm are banned for this year in a move which has caused outrage among some fans.

ttAnd besides the rule changes, the quality of competition has also stepped up a notch.

tyAmong the contestants are several high profile models.

huGilliane Bonheur, 24, hit headlines after vowing to remove her silicone bum implants so she doesn’t have an “unfair advantage” in the competition.

Another contestant Rangel Carlos hit the headlines by revealing she was in a polyamorous relationship with both a man and a woman – and the three are raising a child together.

Playboy model Jeni Summers will make history as the first American to compete in the world-famous Miss BumBum competition this year.

The names of more contestants are set to be revealed nearer the start of the competition in August 7.

Last year it was Erika Canela, from Bahia, who was crowned winner after the fiercely fought contest.

Erika, who has a 42inch bottom, took home a £18,000 prize and a lucrative modelling contract.
