A female character or historical figure like Eva Per�n?

I'm trying to think of a reference, could be literary or historical but it's been driving me crazy: someone similar to Eva Per�n in that she was born into humble beginnings and rose to great status, but was still criticized by people of the upper class, which only drove her ambitions. Her promiscuity might've been thrown around. It's not Lady Macbeth or Anne Boleyn. It's a modern example I think. Please help me figure this out!
