can't not have heard

[Vladv1]

Is it correct to say " She can't not have heard about the events, they are being discussed everywhere"? The example is mine.

Try:

Surely she has heard about the events. Everybody is talking about them.

It's not incorrect and it is understandable. Although plenty of native speakers might use it, it strikes me as slightly awkward. I strongly prefer @Tarheel's version.

Note my corrections above. Don't leave a space after opening quotation marks. You had a comma splice. Between "events" and "they", you need either a semi-colon or a full stop.
Your sentence is possible. It's also possible to say "She can't have not heard about the events ...".
The construction is relatively unlikely from a native speaker. I'd expect something like "I can't believe she hasn't heard about ..." or something along the lines of Tarheel's version.
