It's possible that:
* You're thinking of someone else: There may be a less famous person named Prince Larry, perhaps a local celebrity or a fictional character.
* It's a nickname or a joke: Perhaps "Prince Larry" is a playful name used within a specific group of people.
* It's a misremembered name: It's possible you're confusing "Prince Larry" with another name.
Can you provide any more context or details about who you're asking about? This will help me give a more specific answer.
