The 35-year-old former model defined the affair of Sanders with "Twilight" actress Stewart as the most "horrible feeling" of her life, reported Ace showbiz.
"It was horrible. It was really the worst, really the worst," she said
"I have no words to describe what we went through. But I think, for me, something always has to completely die for there to be a rebirth. And I feel like I'm going through a rebirth," she added.
The affair came into limelight when pictures of Sanders and Stewart were published in tabloids but later both issued a public apology.
