It could mean that there are hidden efforts, sacrifices, or events that lead to someone becoming a star. For example, an actor might have a lot of training, rejections, and personal growth that happen behind the scenes before they become famous. It's like the real story that isn't always visible at first glance.
This phrase suggests that behind every star, there is a narrative that is not always in the public eye. Maybe it's about the people who supported the star on their way up, or the unique experiences that shaped them. For instance, a model might have come from a small town with big dreams. She had to overcome body shaming and lack of opportunities in her early days. All these things are part of the story behind her becoming a star.
Well, 'a star is born behind the story' might imply that the journey to stardom is filled with untold tales. There could be a backstory of perseverance, like a singer who practiced in small clubs for years, facing hardships but still chasing their dream. This hidden story is what actually gives birth to the star we see in the spotlight.
