Plz advice... how to approach this girl.. genuine answers only plz..?

Approach her just as you would a woman your age, but not in a disrespectful or degrading way. Try becoming friends with her first, then eventually let her know how you really feel about her. She might consider you a creep, and she might now. It all depends upon what type of person she is. No one knows, you just have to risk it and find out.
