Megan Fox and "Transformers" director Michael Bay have been in a war of words since 2009 -- and though it may have cost the 25-year-old actress a few film roles, it's also earned her the respect of "Friends With Kids" costar Chris O'Dowd.

"Who wouldn't have a fallout with [Bay]?" O'Dowd, 32, tells The Toronto Sun. "It's one of the sexist things I've ever seen. She called him an a--hole. Well, he is a f-cking a--hole. She's not the only one who has said that. Why has she been singled out?"

For those who have forgotten, Fox once compared Bay to Adolf Hitler on set. After Bay got wind of her comment, producer Steven Spielberg reportedly told him: "Fire her right now."

Though O'Dowd has never worked with Bay, 47, he knows Fox hasn't had an easy time since she was dropped from the "Transformers" franchise.

"I don't know the ins and outs of it, but it's all down to having a fallout with Michael Bay," O'Dowd said. "I would never f-cking watch his films, never mind go and act in them."
