Solution 1: Ask her in a calm manner whether she want to talk about it as a way for her to vent out her feelings and feel better about the situation. Never do something that provokes her or pressures her.
Solution 2: Offer her your support and keep it confidential, reassuring her that she can trust you and it'll work out just fine.
Solution 3: Encourage her to tell her parents in the right and appropriate time that she deems it so. As her parents, they deserve to know but remind her to tell them only if she's ready to do so and the time and circumstance permits it.
