do Ты think Знаменитости have their own Избранное celebrities?...

Uh... I don't know about those of which Ты have listed, but yes, I do believe Знаменитости have their own Избранное celeb.
It makes sense.

Of course they do! It's not because you're famous that Ты can't be a Фан someone else! Here's an example: the ударник, барабанщик of Styx is a Фан of Breaking Bad and RJ Mitte who stars in Breaking Bad went to see Styx in концерт because he's a Фан of Styx... :D

Of course yes!
Justin Bieber was obcessed with Beyonce!!! :D

yes

Yes...it only makes sense. They are real people with избранное like us...only most of us aren't rich или well-known...but everyone has some sort of obsessive side.
