Probably upper-middle class parents that support her financially, enabling to push for her idol dream while not having to deal with the adversity of real life. It makes someone like that especially susceptible to indoctrination from nonstop online politisperging. I've known plenty of people that grew up in well off leftist areas slowly become more moderate as they deal with real life shit. My favorite example is my one friend that started working as an EMT and was super liberal. After not seeing him for a few months because I was in California for business, I come back to find that he's even more racist than I am because he was doing EMT calls in the ghetto. Between getting his ambulance shot at and retarded hoodtrash asking "HE GONNA BE OKAY?!" when he can see the fucking sidewalk through the hole in someone's head, he got a huge reality check.
