Ask her, but don't approach her in an angry manner. Just ask her what's wrong, and if this is true.. if she says it's not, explain to her that you've heard somethings but don't say "yeah but i herd u did so u can just shut ye' gob." not that anyone would say that, but just tell her calmly and don't start anything. if by the end of the conversation you havn't acheived much information, or sorted anything out.. just leave it for now untill she has decided to confront you or say some other things about you.
