To know real personality of celebrities

Don't let tabloid fool you about celebrities behavior! Of course in front of the camera, celebrities know better than to misbehave unless they want to be famous for the wrong reason. I mean, yeah, there's plenty of celebrities who gain publicity through doing stupid stuff. (I'm pretty sure Kristen Steward scandal was a publicity stunt). Do you notice mostly their bad/true behavior's are only known when photo's were leaked, videos were taken secretly, observation from public. oh yes, the only way to know if that person is really who they are on camera, is (i suggest) watch reality TV show.

Even if it's on camera, you can try to act as fake and nice as you want. But prolong exposure can make you forget you're on camera and there, the true colors of the person shows. Be it swearing and cursing, tongue slips, mischievios acts..... you will see and judge it for yourself. Then you decide whether you really like/admire/idolize/love them or not. For example, Keeping Up with the Kardashians. ugh~~ i hate those bitches. They over exaggerate things, fake everything and they act so innocently when facing the public. Yeah right~~ That's why i don't watch them at all, i just wonder why my mom and sis does.
Guys, they can be so charming in this industry but don't let them fool you. Before you fall head over heels for them, think carefully. Again, watch shows! Why? i'll give you reason why.
Lets take for example, korean stars (hot aren't they?) Jung yong hwa-CN blue, Nickhun-2PM and JoKwon-2AM. I watch them on the "We got married" show where they pretend to be married to another celeb (girls of course). Through the show, you see how they interact with each other and I can conclude many things just by observing. Observation! It's powerful. Though it might sometimes be inaccurate but well, i think it's one of the most useful tool. 
What i deduce? I can see that Jung yong hwa might be a really good friend, he pretty much doesn't suit to be a boyfriend. He's the kind that enjoys power and I can see he wants his way at things. He can serenade you into loving him them he'll be cold and sarcastic once you're hook to him. And he's not really romantic or his idea of romantic really doesn't work on girls.

Then there's JoKwon, he's once hell of a fun guy to hang out with. Great friend, considerate, fun, and he's lovable. Girls might like him as friends but not really as a boyfriend.(or he's just not my type, too skinny). He's too shy at times it's unbearable. He is romantic but a little stingy, girlfriends shouldn't expect too much from him. He won't splurge until he's sure. i absolutely love his episode cuz it guarantee lots of laughter and "aww" moments.
For Nickhun, okay, he's really a romantic guy. He's every girls dream guy. Kind, considerate, cute, helpful, generous, romantic, fun... oh the list goes on. This guy shouldn't have any problem serenading a girl, those dimples are to die for. I enjoy watching his episodes and not to mention, plenty of "aww" moments too.

It's not easy to know a person in and out. What you see is how they react to public in general, to know even more, you need to go into a deeper level like friends. That's when they open up bit by bit. Think of it as peeling an onion, it goes from layer to layer. That's how we really know the person, peel their mask. Sometimes good looks are deceiving, write that down.
