Girlfriend destroys windshield

Yesterday something stupid happened. My girlfriend and I cleaned my car together. I was just sucking when my girlfriend asked me what else she could do. I told her that she could still refill the wiper if she wanted. Said she did. She opened the hood. Unfortunately, the windscreen wipers were still folded up and now the windscreen has a crack and the edge of the hood is also scratched. I have to say this now to my assurance. ng report or pay this possibly the insurance of my girlfriend ? Thanks for the information. Greeting Stefan
