Felt like a celeb you have a crush on looked like someone you know?

Ever felt like a celeb you have a crush on really resembles someone  you know? I mean, you have no romantic feelings whatsoever about this person but when you look at the celeb and you see at certain angles there really is a striking resemblance, you're slightly put off because you see it. Do you know what I mean? I may be rambling on a bit but it's like 1.30 in the morning and I had to get this out before I forget. I was watching an old Luce/Rachel(Imagine me & you) fanvid on Youtube and in a lot of the angles Lena Headey resembled my old best friend's mother and i really don't feel that way about her(the mother not Lena Headey cos y'know, who wouldn't?) at all.
