Liberty Ross, 33, has two children with the Snow White and the Huntsman director, was shocked when the allegations of Kristen's fling with Rupert broke, ranting on Twitter and then deleting her account.

She retweeted a Marilyn Monroe quote that said: "Sometimes good things fall apart so better things can fall together," and then quoted poet Maya Angelou, writing: "If you find it in your heart to care for somebody else, you will have succeeded."

Liberty's final Tweet before deleting her account was a succinct "WOW."

Rupert and Kristen have both released statements of apology to their respective partners.

Rupert spoke about Kristen, 22, last month, telling E! News: "She’s got a great spirit, she's really quite rebellious...and feisty and kind of wild. And that's really what I wanted the modern Snow White to have.

"I didn't want her to be timid and I didn't want her to be frightened and relying on men, you know. She's very strong and very driven, and I think that's true in her personal life... She's got a big weight of the world on her shoulders and she carries it incredibly well."
