Actress-model says she felt incredibly vulnerable after the news of her husband Rupert Sanders' cheating scandal first emerged.
Sanders and his "Snow White and the Huntsman's" leading lady Kristen Stewart made headlines in July last year when photos of them kissing in a secluded car park emerged.
The pair confessed to the fling and publicly apologised to their partners - Ross and Twilight hunk Robert Pattinson respectively, reported Contactmusic.
The affair drove a wedge between the couples and Pattinson and Stewart briefly split, while Ross and Saunders struggled to keep their marriage together.
"It was a defining moment. 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," she said.
Ross and Saunders reconciled but split over Christmas and the model filed for divorce in January.
