I over-speculate into this, but I really think Jay was involved in the same drug scandal as Joo Jihoon back in April 2009. Jay said he did something "real srs biz" back around the Again and Again promotions. Joo Jihoon and like 6 others got busted back in 2009 for their drug scandal, and they mentioned there were other celebrities involved :X.
I get not one but TWO whiny emails telling me that I'm wrong, and a reliable source said he didn't do drugs, impregnate a girl, or anything like that. It was a "contract" problem and links me to a shitty formspring. LOLOLOLOL Reliable source that's close to Jay, JYPE, and 2PM. Right. Sure.
So until Jay actually speaks up I can assume Jay knocked up 3 girls at a time, smoked crack, and beat up Wooyoung for cheating on him with Nichkhun. I DON'T BUY ANYBODY'S CRAP.
*A slight disclaimer. I am and always will be a fan of Jay. But seriously, don't take things too seriously :|.
