i don't find it likely.

the reason i say that is because: a) DID is developed in early childhood due to abuse/trauma, etc. b) usually, a person with DID doesn't just randomly create/develop new alters in adulthood. there can be ones that were hidden that were created/developed in childhood during trauma, etc. that can appear at any time though (i recently had that happen.)

it is possible for those with DID to have introjects of various types, abusers, characters from TV/books, etc. which could include celebrities, but i would think those would more likely those they actually heard about/watched, etc. in childhood when their DID developed. otherwise, it doesn't really add up to me how they could have ended up with them in adulthood if they didn't see/hear about them and they didn't exist in childhood as it's a childhood trauma disorder that a child's mind develops to cope.

some say it's possible for adults to develop DID, but i would say that is very rare because it kind of throws out the theory that it's a developmental trauma disorder as adults (unless they already have DID) tend to have more of a sense of self, an integrated personality, etc. (unless they have borderline personality disorder where it can be more split but doesn't include alters even if it does include dissociation).

a lot of things disorder wise look similar and overlap with symptoms, and i could go on and on about all that but won't because i'll just confuse things.

so, no, i personally don't believe this person has DID based on that alone. it might be more of a thought/delusional type disorder, but they'd have to see a professional to figure that out.
