After the affair between actress Kristen Stewart and film director Rupert Sanders was revealed Tuesday, Sander's wife, model and actress Liberty Ross, posted a mysterious tweet and then deleted her Twitter account.

Stewart reportedly cheated on Robert Pattinson with the "Snow White and the Huntsman" director recently, sources confirmed to People Magazine, Us Weekly and E!Online.

"Wow," Ross wrote on her Twitter account just hours before the news, according to E!Online. Then she reportedly deleted her account.

Furthermore, Ross tweeted a more mysterious message on July 23. The actress retweeted a famous saying by Marilyn Monroe "Sometimes good things fall apart so better things can fall together."

While any of the people involved in the affair have made comments, a source close to Kristen Stewart told People Magazine the actress was "devastated" for what she did.

"Kristen is absolutely devastated," a source told People. "It was a mistake and a complete lapse in judgement."

"She wasn't having an affair with Rupert. It was just a fleeting moment that shouldn't have happened," the source said. "She never meant to hurt anyone. She's a good person who just made a bad choice."

The affair was unveiled Tuesday by Us Weekly magazine which claims to have photographs of the two hooking up and not having "enough" of themselves.

Sanders and Ross have two children together.

Some people on Twitter had negative comments towards Stewart.

"Kristen Stewart, how could you cheat on Robert Pattinson with a married man that has children? So disappointed in you," one Twitter user wrote.
