* He's a relatively unknown person: There could be a person named Justin Star who hasn't achieved public recognition.
* You might be misremembering the name: It's possible you're thinking of someone with a slightly different name, or a fictional character.
* You have a specific context in mind: You might be thinking of a Justin Star who is known in a particular niche or community that I don't have access to.
To help me identify who you might be asking about, could you provide more information? For example:
* What field is he in? (e.g., music, sports, business)
* Where did you hear the name? (e.g., a news article, social media)
* Any other details about him?
With more information, I might be able to figure out who you're asking about.
