Liberty Ross Tweets About Husband Rupert Sanders’ Alleged Affair With Kristen Stewart

Liberty Ross expressed her disappointment with the alleged affair between her director husband Rupert Sanders and the star of his latest film Kristen Stewart and what better medium to vent than Twitter.

On Monday, news broke that Stewart was allegedly cheating on her beau and Twilight costar Robert Pattinson with the 41-year-old director Sanders. That's when, 33-year-old Ross took to Twitter to let out some steam, citing a ambiguously-directed quote by Marilyn Monroe.

sometimes good things fall apart so better things can fall together, Ross tweeted on Monday, the quote being from the Women of History account, Yahoo reported.

Ross and Sanders have two children -ages 7 and 5 - together.

Ross deleted her Twitter account after the incident, which first broke on Monday by People. The magazine reported that 22-year-old Stewart had an affair with the married director of her recently released film, Snow White and the Huntsman.

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

Stewart's brief fling with Sanders also was reported by Us Weekly, which said the two were together on July 17 in Los Angeles engaging in a marathon makeout session.

It seemed like they couldn't get enough, a photographer witness said.

While Stewart and Pattinson have never officially announced their relationship in public, the duo have been seen together since the first Twilight film came out in 2008. The source who squealed to People magazine, though, says Stewart's brief fling with Sanders was all a big mistake.

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.

And it appears her bad choice had little impact on her relationship with Pattinson, as the duo were seen together on Sunday at the 2012 Teen Choice Awards, where they accepted the Ultimate Choice Award along with co-star Taylor Lautner.
