Martina Stoessel may only be 17 years old, but she's had quite the life.

The Disney Channel star, who is known for her starring role on "Violetta," recently opened up to 500 people -- most of which were young fans -- about her life, and, more specifically, her autobiography "Simplemente Tini" ("Simply Tini).

Tini stepped onto the stage wearing giant platform heels, which are quickly becoming one of her signature looks, and a green jacket. The first thing she did was thank her fans for showing up to Estación Mapocho in Chile to hear her speak.

"It's crazy that you are here," she said. "They told me that you camped and stayed to sleep, that you were here early. I read it on Twitter and in publications, and I couldn't believe it. The truth is that I am very grateful. I'm happy. People always think that celebrities always have a perfect life and that everything is rosy, and what I wrote in this book is that I am a normal girl."

Tini added that, just like other girls, she is sad and happy about the same things. The idea for her book was born from her being a fan of other celebrities and also having misconceptions about them.

On the very first page of her book, Stoessel explains that she takes off her makeup and spends time at home with her family, who makes her feel grounded.

"I try to go to the movies with my friends," she said. "I try to, in the realm of possibility, have a normal life and at the same time have a professional life, always close to my family and the people who were there from the very first moment."

Tini also said that in 10 years she would love to have a singing career, but at the same time, she's trying to live in the present. She went on to talk about her own idol: Beyoncé. She applauded Beyoncé's talents and said that the singer also makes people feel things.
