Liberty Ross Speaking in Code Before Divorce Filing?

1/26/2013 4:55 AM PST

 Liberty Ross didn't seem like a woman about to file for divorce when we spoke to her just two weeks ago ... or did she?

As TMZ first reported, Ross filed for divorce yesterday from her director hubby, Rupert Sanders, who made headlines over the summer for his fling with Kristen Stewart.

When we caught up with Ross outside of the Chateau Marmont back on January 11, she said the latest with her was simply ... "happiness." (Or maybe she said fabulous. Hard to tell. But still ...)

Was she happy because she knew she was about to dump her cheating hubby? Or was she still in the process of trying to make it work? Watch the video and judge for yourself.
