It's possible that:
* The name is spelled differently. Perhaps a slight variation in spelling exists.
* They work behind the scenes. Tina Gasbarra might be involved in film or television production but not as an on-screen performer.
* They are not publicly known. It's possible this person is not well-known and their work isn't widely documented online.
To help find more information, I'd need more context. Could you please tell me:
* Are you sure about the spelling of the name?
* Do you have any additional details about them (e.g., their role in the project, where they might have worked)?
With more information, I might be able to help you find more details about Tina Gasbarra and their work.
