Personally i dont think tsunade knew until the attack on the leaf village that naruto was the son of the 4th.Does anyone else in the hidden leaf village know that Minato is Naruto's father?? and if not, why wont naruto tell people?! Sakura would fall for him in a second if she found out that he was the 4th's son
Kakashi, yamato, sai, danzo, jariyah,sarutobi, all knew.
And mainly all the older generation that knew minato. on a personal level, not just as the hokage
