#7: Neil Patrick Harris
Whilst so many people have nice things to say about what certain celebrities were like pre-fame, some people didn’t have the best experiences with certain A-listers before they knew what it was like to be famous. There are lots of people who have met this particular celebrity and said that he isn’t the nicest guy going around, so this doesn’t come as any real surprise…

Apparently, the How I Met Your Mother star, Neil Patrick Harris, was a bully in high school… He always acts in such a nice and friendly way…
Let’s face it, he is always a good-hearted character, but that’s the thing about actors; they get pretty good at playing different characters. And it appears that Neil Patrick Harris has a real gift…
