Celebrity crushes : Morally okay?

Would it be alright to have "celebrity crushes"? I just think this one guy is very pretty and really funny and there's that small attraction, if that makes sense. I also talk to my friends about how pretty I think he is.

I don't make sexual thoughts with him (or anyone) willingly in my head. Just wondering, as I also sometimes see people taking it too far with their "celebrity crushes"...
