Liberty Ross filed for divorce from her husband, Rupert Sanders, earlier this week, but sources claim that it wasn’t just Sanders cheating scandal with actress Kristen Stewart that was the reason behind the filing. According to US Magazine Ross wasn’t happy in the marriage even before the cheating scandal surfaced.

“She wasn’t very happy, even before all this happened.  Rupert put a lot of pressure on her to change her life for him and they moved to L.A. for him. She was such a big deal in England — a bigger deal than him even.”

While I’m sure that there might have been issues in the relationship prior to the whole KStew scandal, I’m sure that didn’t help!  I wonder if this will cause any tension between Robert Pattinson and Kristen Stewart too?

Attached are pictures of Liberty leaving her Hollywood Hills home today.  She looks pretty happy to me!
