But at the end of the day, do you really know who Kylie Jenner is? IDK, probably not.

If you've ever met a celebrity in person, I'm sure he or she either lived up to your expectations or left you feeling disappointed.

Either way, it's hard to really know what famous people are like until you meet them for yourself.
