Actress/model Liberty Ross has credited a New York Fashion Week catwalk appearance with kickstarting her recovery after her husband Rupert Sanders' cheating scandal, revealing she felt "incredibly vulnerable" after news of his fling with Kristen Stewart first emerged.

The director and his Snow White and the Huntsman leading lady made headlines in July (12) when photos of them kissing in a secluded car park emerged.

The pair confessed to the fling and publicly apologised to their significant others - Ross and Twilight hunk Robert Pattinson.

The affair drove a wedge between the couples and Pattinson and Stewart briefly split, while Ross and Saunders struggled to keep their marriage together.

Ross has now spoken out about the aftermath of the scandal, revealing a New York Fashion Week catwalk appearance for designer Alexander Wang in September (12) helped her regain her personal strength.

In an interview with Net-a-Porter's digital magazine The Edit, she says, "It was a defining moment and I felt honoured to be supported by him (Wang) during that difficult time.

"I was not in a good way at that point in my life and felt incredibly vulnerable. Doing the show was daunting, but it was wonderful to get up there, show my strength and shine for someone who believes in me. I was very grateful."

Ross and Saunders reconciled but split over Christmas (12) and the model filed for divorce in January (13).
