Does Delores Umbridge get raped in Harry Potter?

Okay, so my friend said Umbridge got raped by Centaurs when they took her away. I mean I don't think they ever imply she gets raped but she said they did. Is there any where in the 5th book or movie that implies she got raped. I would like to know if this is true or not.
Update: No, she was not killed. Because she comes back later in the movie/book and in the 6th book/movie
