Photos: Meet the Bootylicious Mother & Daughter Duo Contesting For Miss BumBum Beauty Pageant

A mother and daughter competing in Brazil's Miss Bumbum competition have revealed how their obsession to win the coveted prize led to the mother's boyfriend of six years, walking out on them.

Bruna Ferraz, 35, and her daughter Eduarda Morais, 19, both admit they are desperate to be crowned the country's queen of shapely bottoms.

With both women virtually neck-and-neck in the race with less than two weeks until the grand final on October 9, Bruna and Eduarda both claim they will do anything to pip the other to the post.

'Winning means everything to me, it will change me life forever. But I know it means everything to my mum too,' said Eduarda.

"Now we're both in the final it will all depend on who's got the most beautiful bottom. I admire my mum's bottom. I hope mine will be as firm as hers when I'm her age."

It is the first time a mother and daughter have reached the final of the popular pageant, now in it's sixth year, which also debuts a separate contest for over-55s this year.

In a public vote which whittled the original 27 contestants - one from each Brazilian state - to the final 15, daughter Eduarda came 11th with 450,000 votes and mum Bruna 12th with 400,000.

But when it comes to their assets, mum has the slight edge. She has 43 inches of bottom, compared with her daughter's 42 inches.

Despite the intense rivalry, both women, who live together in Porto Alegre, southern Brazil, claim they are helping each other in their quest for the trophy - especially since Bruna's long-term partner Pedro packed up and left nine months ago.

Bruna's long-term boyfriend Pedro, packed up and left nine months ago. The plumber claimed he was fed up with the pair constantly comparing their backsides - although Bruna believes he was actually jealous of the male attention they started receiving when they announced their candidatures.

Bruna said: "When we got accepted on the competition we were both pretty euphoric. It was all we talked about, and what we had to do to win.  He ended up giving me a choice, pull out or he'd leave me. We'd been together for six years, it wasn't the most perfect relationship but we were living just like husband and wife. 

"But it was an easy decision to make. I would never let anything get in the way of realising my dream, and certainly no man. He actually accepted my decision without any problems, we didn't even argue about it. He just understood that the competition was more important to me than him, and he moved out.'"

With him out of the way, Bruna, who owns a company which sells human hair extensions, says she is even more focused than ever on winning the infamous competition.
