Actually, Kristen Stewart's career is doing just peachy. I'd argue that her career is in a better state than Robert Pattinson's -- and for good reason, because while she's not a great actor, she's better than him. Elizabeth Taylor was condemned by the Vatican and it didn't hurt her any. Gwyneth Paltrow cheated during her marriage (and in most of her relationships, including the one with Brad Pitt), and I doubt anyone would care if she weren't so generally elitist and insufferable, and it didn't hurt her career. As it is, no one really seems to care, and is much more intent on talking about how completely evil her husband supposedly is for cheating on her. Speaking of Brad Pitt, Angelina Jolie's probably the biggest female movie star in the world.

Then there's what I've seen in my own life, which is that if anyone cheats on anyone else, so long as it's not on the level of "constantly visits prostitutes," no one outside the family gives a damn, and it certainly doesn't do anything to someone's career, because if nothing else, people at work don't even know about it.

Cheating really is not a big deal to people not involved in the relationship except to the gossip world and the political world. It is a seriously not-big-deal within the Hollywood-pop music world. Now, men have most of the power in that world, and if someone without so much power cheats on a power player there, they're in trouble, so it's more likely that a woman will be in trouble for cheating than a man simply by the odds. But the evidence doesn't show that it hurts a woman's career to cheat generally.
