it is a person who is not a guy. "guy" can be defined as "male" of any age. are you saying that the person is not male? You also said that the person is not fictitious, which leaves out someone like E.T. whose gender is unknown. is the person alive? EDIT: I read that question as "is or WAS the person a guy."
is she generally considered "well-known?"--and for the purpose of the question let's define "well known" as someone that 33% of a random selection of people in any mall in America will have heard of.
is (or was) she on tv on a regular basis for some period of time (which could include a reality show)?
I would need help. I suspect that the next answer will be "yes," and then I would be clueless. Was or is she on a reality show (which includes american idol)
