To the op,best thing to do is get her to meet you at the bodyshop with the car and get a quote your both happy with and that you agree with the bodyshop that she will pay for it and no corners cut.

By all means mention it to your insurance company in an informal way by stating everything's in hand,you know the girl involved and the damage is so minor that it's not really worth claiming over right now but you'll see how it plays out.

Point is she would have to be very clued up and stupid to try and get away from the claim as its a rear ender and she's a youngling in insurance terms,probably a grand excess.

I'd say your pretty safe overall.
