Did Jessica Egg Cash On?

Before he got into a confrontation with a photog over a side mirror last night, Cash almost got into it outside of Borders in Beverly Hills yesterday...with Jessica egging him on!

When one pap tried to repeatedly make conversation with the couple, Jessica, who's usually so tight-lipped around the paps, turned to her man and said "He's a pretty boy, babe, he doesn't know how to fight!" Cash seemed just as surprised as we were that Jess was talking in front of the cameras but kept his cool, even when a photog taunted him later in the parking lot.

But I guess everyone has their boiling point, as we saw later at Foxtail!
