Big Snubs
According to Griffin in one of her books, she and Kutcher were hired as hosts together. Apparently, Kutcher wasn't keen on listening to her and working with her. He snubbed her at every chance he got... He even interrupted an important conversation between Griffin and P. Diddy! Now, Kutcher hasn't refuted this story or anything, but it's still a bit odd for Griffin to come out and say such things.
