Um.., actually I didn't comment on their relationship status or feelings, but just the nasty unsourced rumors.
But because you brought this up, I wouldn't read too much of their "body language" basing on a very few creeper and pap shots. Besides the Kate Bosworth haters, obviously current Alexa haters used to say the very same things about her and Alex, like Alex always looked miserable and his family hated her, you see a pattern here? Or if Alex ever looked happy the photos were staged for PR.
I've seen enough celebs shoving their tongues down each others throats and the very next day they've split, so it's pretty hard to interpret anyone's body language, unless you're a telepath
