Yeah, she's being a little flirty, but both of them are in strong long term relationships. Where not talking about a bunch of young insecure kids here.
At some point you grow up and realize that you cant stop someone from cheating. You just have to make sure they know if they break that trust, you will in know way accept it.
Plus they became friends on "The Legend of Bagger Vance" ten years ago.
I dont mind my girl being a little flirty. Its good for her to go out have some fun and feel sexy. If you have a girl you cant trust than you an upgrade.
Sh!t, I wish Charlize would flirt with me a little, cause she is sexy!
