I'm in love with a rockstar

I have heard of people talking about celebs crushes and all and telling me that they used to feel exactly the same way as me but there is something else that I'm too embarassed to splurge further...
I'm 22 and will be graduating from university soon but I'm still insanely childish( or stupid) for still being in love with a rockstar! Every now and then, I'll tell myself that "he's way out of my league and that he can get any girls that he want" but most of the time, I'll tell myself "so what if he's a rockstar? He's still a human being with a heart and who knows? Maybe he'll love you!"
And with YouTube, it doesn't help at all because from there, I saw a different side to him and I'm even more convinced that he's the one for me. I fell that we are so similar and if there's any differences, it's only to complement us.
So that's exactly how I feel. I do try to laugh it all and try to tell myself that there are probably other girls who fell the same way too. But it doesn't seem to work. Is this normal and what else can I do to get a reality check? My family and friends think I'm crazy but here i am, still groping on the impossible.
