Andressa Urach, the Miss BumBum contestant who almost died from an infection caused by fillers, is revealing in a tell-all book how the fame from participating in the competition led her to a life as a high-priced escort who slept with various wealthy men, including soccer star Cristiano Ronaldo.

According to the Daily Mail, in her upcoming book "Morri Para Vivir" (Die to Live), Urach is revealing details of how the competition ruined her life. 

The book follows her life before the competition and how it began to spiral out of control after she became a contestant. It is Urach's way of coming clean after her near-death experience, which she called a punishment for her vanity.

"I became, unfortunately, one of the most expensive and desired prostitutes in Brazil. My body was toned, perfect, due to all the plastic surgery I had and anabolic steroids I took, and I aroused attention," she reveals in the book, which Urach has been promoting on Instagram.

Like many of the Miss BumBum contestants, Urach became a sex symbol in her native Brazil. This attention led to a series of sexual encounters with some of Brazil's most famous men, as well as put her in very dangerous situations.

"I turned my body into a cheap piece of merchandise," she explained. "I handed over my intimacy to hundreds, who knows, thousands of men in just 27 years of life, starring in the most humiliating scenes for any woman. Rich and poor, maniacs, perverts, robbers, paedophiles, sadomascochists."

Urach's encounter with several soccer players, including popular Portuguese superstar Ronaldo, came in March of 2013. According to Urach, Ronaldo was infatuated with her and asked her to come and see him.

"I couldn't believe I'd have the chance to have a romantic encounter with one of the planet's most revered footballers," she said. "I didn't want to know about getting paid for this trip. No amount of money would pay for the success of being at the side of Cristiano Ronaldo, I thought."

According to Mundo Deportivo, Ronaldo has denied any relationship with Urach, which the Brazilian model claims occurred while the soccer star was dating Russian model Irina Shayk.

In her book, which is set to be released in Brazil in late August, Urach also claims Ronaldo was unfaithful to Shayk with nine other women.
