Chanel Beauty has enlisted transgender model Theodora 'Teddy' Quinlivan for its latest campaign.

Boston-born Teddy, 25, shared the news on Instagram with a sentimental post about the personal highs and lows led to this moment saying her 'whole life has been a fight'.

'I find I don't cry anymore when things are sad, but isn't it interesting when we shed tears in moments of triumph. This was one of those triumphant cry moments for me,' Teddy said of the modeling gig with Chanel Beauty.

As part of the campaign, Teddy debuts a 'five minute' sun-kissed and bronzed makeup look using Chanel products.

With her enviable cheekbones, Teddy shows social media users how best to apply Soleil Tan De Chanel bronzer, Le Volume De Chanel mascara and Rouge Coco lipstick in the shade Légende.

Posting the video and associated images to her personal feed, Teddy reflected on the difficult experiences she had had since transitioning at 16 years old.

'My whole life has been a fight. From being bullied at school consistently, kids threatening to kill me and going into graphic detail how they were going to do it, my own father beating me and calling me a f**ot, to receiving industry blow back after speaking publicly about being sexually assaulted on the job...' she wrote on Instagram.

'This was a victory that made all of that s**t worth it.'

'I had walked two shows for Chanel while I was living in stealth (stealth meaning I hadn't made my trans identity public yet) and when I came out I knew I'd stop working with some brands, I thought I'd never work with the iconic house of Chanel ever again,' she added.

'But here I am in Chanel Beauty Advertising. I am the first openly trans person to work for the house of Chanel, and I am deeply humbled and proud to represent my community.

'The world will kick you down, spit on you, and tell you you're worthless,' she went on.

'It's your job to have the strength to stand up and push on, to keep fighting, Because if you give up then you will never experience the tears of triumph. Thank you to everyone who made this dream a reality,' she concluded.

On her Instagram stories, she told her audience that this is an 'exciting time' for LGBTQ individuals.

'Especially if you're [transgender] because trans girls are just out here f**king killing it,' she announced.

'There is no glass ceiling that is unbreakable, like this is our moment to seize the world and we just have to keep fighting and keep getting ourselves out there and making a difference and bringing exposure to the trans community to the forefront of the global stage.'

Teddy has had an impressive runway and editorial career since she was discovered by Nicolas Ghesquière, creative director of Louis Vuitton, in 2015.

During New York Fashion Week in September 2017, Teddy came out as transgender in a series of videos posted to Instagram. Up until then, she had publicly presented herself as cisgender.

'My name is Teddy. I'm transgender. I remember living my whole life as male, but feeling like I was playing a part,' she said in the clips.

'I always knew I was female like just in my soul, in my heart in my brain. I kind of knew I had to pretend to be male to appease like everybody else.'

Hours after making the announcement, she walked the runway for Marc Jacobs, which she dedicated to murdered trans women.

'Today I walked for Marc Jacobs, but I also walked for Venus Extravaganza, Mesha Caldwell, Jo Jo Striker, Jaquarrius Holland, and countless other trans women who's lives were cut short due to senseless violence and lack of understanding,' wrote Teddy at the time.

Her openness was widely praised by the fashion industry.

Teddy has previously spoken about her mom's support in her decision to transition.

Her mom helped her find doctors and a school that was more accepting (Walnut Hill School for the Arts).

'She [her mom] was like, 'Okay, if you're going to transition, you have to really do it — take the hormones on schedule, and be responsible about it,' she said.

'For the first time, I got to decide my pronoun,' she said. 'I had this incredible art teacher who asked me, 'Do you want me to call you she or he?' That was revolutionary. I chose 'she,' and from then on, it stuck.'

Since starting her modeling career at 22, Teddy has worked with Louis Vuitton, Giambattista Valli, Moschino, Valentino, Versace, Dior Haute Couture, Diesel Black Gold, DSquared2 and Alutzarra.
