Ehhh, depends. Not quite sure what the ballpark of the term 'superstar' is, but I can definitely see her staying in the industry, giving hits, having fans, and remaining relevant in the public eye for many years to come, especially if KJo continues to help her. So far, wherever she is, is due to KJo backing her. He's the one giving her the best directors, freshest stories, hyping her up, giving her publicity, etc. If he continues, she'll remain in the public eye/ in movies for a really long time.
But if she and KJo fall out, idk. Contrary to most people I think she isn't THAT charismatic or anything. She can be great on screen sometimes, but other times she isn't as much. And she's not really that good looking. She can only be called cute, which I think could maybe limit the roles she can do? Idk. Plus she isn't the best dancer or anything. If she works really hard, then maybe she can make it?
