How do you get to know your favorite actress?
try to find out her usual daily routine and try to be in those places and hopefully catch her there. try shopping stores/malls where she likes, that's a popular one for the press.
find out where the next opening night red carpet ceremony is for the current film she is in and try to get an invite there.
go to an awards night where she will be and hopefully you can meet her.
enter a contest to meet her, which would be rare to win i guess.
contact her through a close friend/family memeber of hers.
all of these would seem hard to do but its worth a try at least.
