CATWALK PICS: ALEXANDER WANG S/S 2013

In the video, which was filmed before the New York designer's spring/summer 2013 catwalk show, the mother-of-two opens up about her modeling career, her first career high getting shot by Mario Testino for British Vogue, facing her fears on the catwalk and feeling blessed in her life.

'I have a really good balance. I’m very happy with my life, and I’m lucky. I have good people. I have two amazing children,' she says.

Ross made a triumphant return to the catwalk - her first Fashion Week show in two years - for Wang's Spring 2013 collection during New York Fashion Week in September, looking fierce in a white hooded mac and cut-out-detail skirt, but later admitted she was 'totally terrified' of the experience.

In Wang's Confessional, the model also speaks out for the first time about coping with her husband's affair with actress Kristen Stewart, whom Sanders directed in Snow White and the Huntsman, which Liberty also starred in.

'I believe that we’re all on journeys and we’re all given lessons at certain times in our life...'

'Sometimes when things seem really bad, you have to be able to see the good and learn from it and more forward as graciously as possible.'

She continued: 'This year was the end of some things and the beginning of something else. Beginnings and endings are always really exciting.'

According to designer Alexander Wang: 'Every time a model transitions into acting, I feel like the [fashion] industry is losing a star; it was so great to have her tell her story.'
