Unfortunately, their relationship didn’t last, so in 2015 it was already history.
It seems that the real reasons for the separation are not nearly as exaggerated as the media presented them. Sean Penn and Charlize Theron simply decided to break up because they didn’t fit in so well.
Currently, the actress from Mad Max Fury Road and Atomic Blonde claims that the subject of marriage between her and Sean Penn was never discussed, although information appeared in the public space according to which the actor asked her to be his wife in Paris, in November 2014.
I guess we will never know what the truth was.
