Champagne is the root of all hangovers... at least for Jaejoong
YC: Last night, we went to a club with our US dancers and people from our company. I got there first, then Junsu, then Jaejoong. He was late because it was one of his friends' birthdays. When he came, he was already.... smashed. Apparently they had drunken 40 bottles of champagne at the birthday party. He stayed the latest at the club because he arrived the latest, which is probably why he doesn't look that great right now. Pretty sure he's still hungover.
