Teenage girls are often more out of control than teenage boys. From personal experience, I'd say it's because social status is paramount to them, and they'll do whatever they have to to make it to the top tier of the popularity ladder. Obviously, this varies depending on the girl. I have two relatives who went through this rebelious stage and were lucky enough to make it out unscathed. One had lenient parents, the other strict. Both almost followed a mirror image of each other. It started with hanging out with friends late, progressed to some heavy drinking, fights with parents over both of those, dabbling in drugs, laying every guy they could get their hands on, and finally graduation from high school. Blessedly, it stopped there both times.
I think you just have to hope that you've instilled the right values in them from the start and maybe they won't lose themselves in one of the many pitfalls they play chicken with.
