After turning heads in 2011 as an androgynous male model who would blaze through the womenswear runway shows for prominent fashion designers like Marc Jacobs and Jean Paul Gaultier, Andrej Pejic is once again making waves. But this time, it's because he has confessed to undergoing a sex reassignment surgery earlier this year, and now goes by the name "Andreja."

"I always dreamt of being a girl," Pejic told People magazine, speaking about her recent surgery. "One of my earliest memories is spinning around in my mom's skirt trying to look like a ballerina."

But the Serbian-born model said that she realized it was time to put away the dolls and skirts after a "social message from my brother and friends at school."

"I kept my dreams and my imagination to myself and became pretty good at acting as a boy. But I was hiding who I was," she said.

Then, at 13, Pejic wandered into the library, went on Google and typed 'sex change.' "My life changed," she said. "The Internet gave me the sense that there were words to describe my feelings and medical terms." Finally, the model knew what he wanted to do-become a woman.

Speaking to People, Pejic says she wants to share her story to the world because "I think I have a social responsibility. I hope that by being open about this, it will become less of an issue."

She also kept mum about what time of surgery she had, much like Laverne Cox, the "Orange is the New Black" star and the first ever transgender actress to be nominated for an Emmy. "I completely agree with Laverne Cox and [former People.com staff editor] Janet Mock," she says, opting to focus on advocating and activism within the trans community instead. "What's in between anyone's legs is not who they are."

Pejic also took to her official Facebook page to thank fans who showed their love and support for the model through the years.

"I like to think that my recent transition hasn't made me into a different individual. Same person, no difference at all just a different sex. I hope you can understand that," she shared on her page.

"As a transgender woman I hope to show that after transition (a life-saving process) one can be happy and successful in their new chapter without having to alienate their past. Most importantly differences should not equal divisions, let's all stand together in union," she wrote finishing with the hashtag, "#betruebeyou."

Kudos for the courage, Pejic!
