Lily Costner’s Career and Net Worth
- Lily Costner is a singer and songwriter.
- While talking about her professional life, her dad told The Huffington Post,
Lily is an amazing singer and songwriter. She can be a really huge star if that’s what she wanted. I’m not sure she wants that. She’s really gifted. Lily’s way is not to knock doors down. I think she wants a quality of life. She’s seen the quality of life that we’ve had and sometimes the idea of stardom, I think, is a mystery to her. She’s content with performing. She’s not a person who is trying to angle how to go faster and go higher and go larger. It’s just not how she’s built. She has an amazing talent. Does she want to give it to the world? I don’t know.
