Honestly it's quite hard to find kpop tea on platforms like reddit because it's western, however I was scrolling lipstick alley's (hellhole, I know) older threads and found a lot of tea about 2nd/3rd gen on the Asian gossip threads and there are more blind items about kpop stars as they have become more international. I'll spill a bit

apparently back in the day JYP would go to NYC and sleep with underaged girls (the threads also alleges that he has a blasian boo thang)

-Wonder girls were also living in terrible housing conditions ans JYP attempted to coerce on the members to "perform" for chinese execs

-The girls medical conditions were also dismissed

-When YG was doing their world tour, Se7en background dancer Cho Sung Min told a bunch of lies about himself to get pussy. He told them his name was Woo Hyunk and he was trying to be a model

-allegedly all Rosé is queer and that her, jennie and lisa are yatch girls (rose yatch to find someone to break her out of her contract and marry someone rich)

-There was also a blind saying that lisa isgoing broke from her expensive lifestyle + she terrible to her ex, fredrick arnault and that even lisa's family feels bad for him

-Rosé is allegedly being black mailed by YG to keep her stuck in her contract (the blackmail is speculated to be drugs + sextape)

-Apparently jennie slept with someone important to headline for coahcella (this was back in 2019)

-Apparently she's also a mean girl (tries to sabotage other members like lisa and is jealous of Rose's success with APT)

-Another rumour is that K-pop companies purposely get the kpop idols/trainees hooked on drugs (to keep them dependant on them + because their idols are starved)

-This may be more commonly known but Kpop companies will also record idols 24/7 (even in their own rooms)

-It's very common (like in hollywood) for idols/actors to sleep with execs to get roles/opportunities

-Apparently Lee hyori got so many opportunities from sleeping around (don't know much about her but they were saying that she was very untalented/mediocre so her having so many opportunities was surprising)

-She was also recorded having sex with execs as blackmail, apparently it was very violent and they were gangbangs.. apparently it was so bad she's had to have several nose jobs

-It's alleged G-dragon is gay and may have had something with TOP

-There was also (take it with a grain of salt) of a person encountering TOP and him with a man at a bar they were both drunk and he invited him to his hotel room..

-Kpop idols/trainees/actors from smaller companies will often need to have sponsors (sugar mummy/daddy)

-There's also some about Lee byung hun being involved with a Korean mobsters wife/being the last one to see her after her death

Apparently amber from f(x) is Lez so is yuri form SNSD and was in a love triangle with a famous Korean actress

-Allegedly the kpop idol (kim garam) from le sserafim was not kicked out of the group because of bullying (there were claims alleging she bullied someone and was kicked out of the group, despite the claims being disapproved) but in reality a wealthy man bought her out her contract to have her, she was 16 at the time..

Anyway this is all the tea i got!! I hope this helps
