Hmmm? Wait, if you realise they ARE human beings then logic says you DO have a chance to date them...even if it's the 1 in a million kind of chance...XD
Anyway, celebrity crushes (and any other crushes in general) and even being jealous and all that...they are things you understand only if you've felt them.
At least, when I tried to explain to anyone who never felt that way..they weren't able to understand so.....it must be that way.
At any rate, the pics above are all from photo shoots and PVs. Normally one would feel a lot more jealous if it was a picture like those paparazzi take of various celebrities with their partners being all huggy/kissy in private...XDDD
