Help me find this book! Ya/fiction/ teen actress

My brain just pulled up a very small memory of a book/series I read wayyyyy back when.

The most I can say is it’s about a teen girl, 16 or so and she’s a long time actress on a tv show. It follows her life working on the show. It is fiction. Ya style. Maybe there’s a hint of mystery? And I think the tv show gets cancelled and it follows them closing down the show?

Please help because now I can’t let this go!
