exactly--it is VERY obvious in the photographs.
I truly believe that Stern saw Birkhead as a true threat. I think Birkhead was her longest romantic relationship with a man ever since she became a household name. Stern always looks like he some little dog begging for her attention in the pictures that are taken of both of them. Stern was her lawyer and butler as well as her "pet". Stern just kept hanging around hoping that one day Anna would see him in a different light. Then came along Birkhead who is actually younger and better looking and I bet Stern did everything he possibly could to sabotage that relationship.
