This is something I found online about an ex YG trainee, dont know if it is 100% true.
A couple YG artists involve themselves with a lot of drug use.. It is their way of freedom and their way of expressing themselves. Honestly, all those beautiful tunes come from the essences of being intoxicated most of the time.. I hate to say it. The process worked so well that even trainees began to take it into consideration. But yeah, the artists that use it most are Jiyong oppa, CL, TOP and Teddy. I know this because every time I would pass Teddy’s office, the scent would linger from several feet away. The smell was most heavy during times when CL or GD were in the recording studios, also TOP just simply reeks in the stench. Jiyong is an incredibly talented artist, he’s the money maker for YG, excluding PSY. Aside from his career, he is pretty down to earth, but most of the time he seems to be very tired and has dark circles all the time. I don’t know if the rumor about him being a sex-addict is true, but I hear he messes around with a lot of people. He goes to clubs a lot, the older trainees see him in a lot of underground clubs, he is always with Yang Seung Ho. Back in 2010 Taeyang was a very chill person, he wasn’t too much into his new style yet, but he was very “original”. I actually prefer Taeyang’s Wedding Dress days opposed to his nowaday looks. But yeah, I heard that YG himself was fixing Taeyang’s style up because as an idol he can’t be “ordinary”. TY’s whole style is changing up due to the way everyone sees him. He’s a very sweet guy and no he isn’t dating anyone (as of 2012), even though he released the I Need a Girl song. He is losing himself to everyone’s critiques and I hear he self-doubts himself a lot. Daesung honestly didn’t come around much, he doesn’t seem to show much interest in many things. I heard that he is extremely close with some SNSD members and they hang out a lot. He’s a pretty funny guy and always exaggerates his expressions when he is easily fascinated by things. When trainees show off, he is the first to react. Seungri was almost ALWAYS around the girl trainees whenever he would come around the building. He flirts a lot and isn’t afraid to take advantage of an obsessed trainees. He’s kind of weird, just my opinion, I feel like he’s a try hard, being cool or funny just doesn’t come naturally to him, he always seems to TRY doing those things, but that’s just me. TOP oppa is very cold. Not as in MEAN but he just doesn’t talk much when he’s around. He always seems tired and walks around with a mad face. I once had a small conversation with him and he reeked of alcohol. As of 2012, rumor says he was depressed because he had an identity crisis and went through a rough patch with a past girlfriend. Overall Big Bang is alright as just normal people, I’d say the most down to earth is Daesung because when he comes around he always makes others laugh and continues to just be himself. Big Bang isn’t that close anymore and have grown distant. The only members who still keep in contact are GD and YB. 2NE1 is honestly losing their whole touch.. I still keep in contact with my friends who are still trainees and they tell me many things while conversing over the phone, so the more recent info are just from my friends. Recently CL has been extremely overconfident and conceited. She knows she runs 2NE1 so she takes advantage of her position. She is very arrogant towards Dara and doesn’t pay much attention to Bom and Minji. Dara is very, very nice, so CL knows she can be as mean as she wants to Dara and nothing would happen. I remember one day I stayed late after practicing at the building and I just so happened to hear CL taunting Dara in the other hall, she said something like “Ssandara, what if we switched roles, I would be face and you main rapper, it would be good for me but not so much for you” or something like that and she laughed. I didn’t hear a reply from Dara. I mean of course it could have just been simple jokes, but hearing no reply and no laughter from Dara at all raised up some questions. CL has let her fame get to her and she honestly isn’t the same girl as before anymore. I remember during their Try To Follow Me era, CL was an extreme tom boy and didn’t like much girly things and make up as well. She was a very passionate rapper. But nowadays she wears layers of makeup and always dresses in brand clothings and uses her sexy features to her advantage. People say CL is the baddest female, but I don’t think so. Sure she represents all rebels, but in ways of being a bad girl, like going to clubs, getting wasted and high, not being afraid to curse out another person, etc. But she doesn’t represent girls who need to break away from the shell that society holds on women. If CL was a bad girl, she would have shaved the side of her hair for their I Love You comeback, but she was too obsessed with her current hair, she taunted the stylist to give it to Dara saying “She needs more attention anyways”. I know this because I am good friends with one of the hair stylists and she told me. Enough of CL, now onto Bom. Bom is addicted to plastic surgery, any flaw she can find on her face, she gets it fixed right away. Due to this, it is one of the reasons why 2NE1 doesn’t actively involve themselves too much in things, because it would either have to be done without Bom or with a patched up Bom. She is very hilarious, she always comes to encourage trainees in funny ways, examples won’t do any justice. Minji is a quiet member. She isn’t too close to the others because she would rather revolve herself around other things. She is seen to be on the phone a lot with friends and she is always alone. When seen with the other members, she doesn’t interact much, just usually walks on the side or in the back. Minji, although talented, she seems to have lost her love for dancing and just does it because she has to. Now Dara, the only member left that seems to still have everything together. Since she is always criticized about her talents, she is an extremely hard working member. She loves proving everyone wrong and spends hours in practice rooms, usually the last to leave. She is closest with Bom, for they kind of went through similar things in the entertainment and kind of had each other’s back since day one. Dara hasn’t let fame get to her yet and she continues to support everyone in YG including trainees, she always comes around to help out with training for modeling and acting. Not much is she seen helping with vocals or dancing though. I’d say Dara is 2NE1’s last hope if they ever want to unite as an actual Idol Group. That’s all the idols I can really talk about, I barely ever saw PSY, when I did, he was just walking around the building. Gummy isn’t around much. Sean’s children are the sweetest little things! Their family is just perfect. Sean and his wife always visit the company with the kids, when they come around, YG’s wife and their daughter Eunjoo come around too. I didn’t stay long enough to meet Lee Hi and Akdong Musician.. Oh! I almost forgot to talk about YG himself.. He is actually a really good CEO. Although we don’t see him much, whenever he comes around he gives the best advice and critiques. He isn’t afraid to make us cry as well. When he comes around, all backbones stand straight and the room becomes quiet. YG hates trainees who cannot dance, he sees them as a waste of time and effort. He is somewhat a pervert, if a trainee is very pretty or easily gains sympathy points, they get away with things from YG, he loves aegyo from sweet, innocent girls but what Ahjussi doesn’t.. When evaluating trainees, if he is interested in your performance, he is seen to be bobbing his head and isn’t on beat. If he is not interested, his arms are crossed and he takes multiple deep sighs. President YG is a very intimidating guy, honestly if he wasn’t the CEO, I would have probably disliked him a lot, but being President, he needs that kind of aura and it definitely works for him.
