It's possible that:
* The name is misspelled: Double check the spelling and search again.
* The person is not a well-known actor: They might be a relatively unknown performer, or they may have worked in regional cinema or independent projects.
* You're thinking of someone else: Perhaps there is a similar name that you're mistaking for Kirti Singh.
To help me find the correct person, could you provide any additional information:
* What role did you think they were in? (e.g., a specific movie, a character name)
* Where did you hear about them? (e.g., a website, a friend's recommendation)
* Do you have any other details about them? (e.g., age, nationality, any other projects they might have been involved in)
With more information, I can be more helpful in finding the correct information.
