Liberty Ross finally opens up about the affair with Kristen Stewart and her husband Rupert Sanders, in the new issue of Vanity Fair.

The British model turned actress takes part in the candid interview , discussing the distress she went through after photos of Stewart and Sanders kisisng surfaced in July2012, confirming their act of adultery.

Kristen met the British film director on the set of 'Snow White and the Huntsman' which she starred in.

"It was horrible. It was really the worst," she told the magazine's December issue. "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."

The mother of Sanders two children explained how her cheating husband revealed his affair to the 'Twilight' actress approximately 20 hours before the paparazzi photographs emerged online.

Ross's brother and former friend of Sanders, Atticus, who is an Academy Award­-winning composer, also spoke with the mag.

"It was f**king crazy," he said.

"To some extent at that moment, Rupert was in denial, and Liberty didn't know what was going to happen.... I'm texting people because I know this is going to be huge. I knew this had all the makings of what our world has become. This is going to be fucking big, and Liberty needs to be protected. It was about it not destroying [Liberty]. I don't think people understand what being in the eye of that storm is like."

Atticus really did look after his younger sister, he called up a friend who provided Liberty and her children an escape up state, away from the media frenzy that was expected to follow.

"I was able to be there completely secluded," Ross stated. "I just visualized [being] this sort of Masai warrior. I was just going to stand very still and very strong, and just let it all roll past me. I tried to keep as far away from it as I could and to understand that this is my family and it's the most precious thing to me."

After the affair was public knowledge, Sanders wrote a public apology to his heartbroken wife and affirmed that he wants to keep his marriage together. Ross simply could not accept.

The 35 year-old model said, "I'm not a quitter, I've done everything I could to be the perfect wife and mother and really support my husband. But I just didn't have any more to give, you know?"

Liberty filed for divorce in January of this year (2013) and felt they'd "lost [their] real connection." But despite all the heartbreak, Ross still managed to show her classy nature and spoke highly of the disgraced director.

"We were together for 16 years, and that in itself is really beautiful. And we've created two exceptional lives together," she admitted.
