If by "real", you mean "real poseur", then I agree.
What bothers me about her is that, she went into AI with a forced rocker image and just came across fake and affected - "LOOK AT ME! I'M THE TOKEN ROCKER CHICK!" when clearly she isn't.
Black-dyed hair, making rock gestures at the camera , and wearing a tounge-ring does not make a rocker.
Her phoniness showed during her abysmal performance of "Paint It Black" by The Rolling Stones on British Invasion night - a song she has never heard of and had no idea to emote.
If she remained true to herself (a pop singer), then I'd have no problem with her.
