Thanks for your reply, could you give me a little more into the middle part though as it is completely confusing me.

I understand До as before and it causes the following to take the Genitive, right? But then how come the Genitive Masculine/Neutral is being used rather than the feminine "той"?

So literally it is "before that" and then followed by "как" which throws me off even more... before that, like, it became famous??? [до того, как она стала знаменитой?
