C.L.
Could you tell her to focus on the positive. Sit down and the two of you make a list of all the things she is grateful for. What does she get from that behavior. Even though its negative attention she gets your attention.
Next time don't make a big deal about it. Act like it doesn't even bother you. Do this every day..eventually I bet she will change her behaviour if she gets no reaction from you.
Good luck.
