I remember my childhood celebrity crushes were on both members of Kriss Kross, and in high school I had a major crush on Allen Iverson and my current Crush is on Layzie Bone from Bone Thugs N Harmony.
Personally, I never heard of dudes having celebrity crushes. I’m sure they’re out there, though. I used to like Jennifer Connelly until I was almost 30yo (not in the obsessive, idol-worship sense), but after that I don’t care much for celebrities.
