Is it illegal for my land lord to share what I pay in rent with the other tenants?

We have unmarked parking spaces where I live, my downstairs neighbor is home more so generally parks in a certain spot. I had the opportunity to park in this spot so I did because parking is very limited (house not apartment complex). She came knocking on my door irrate that I parked in "her spot" and that she deserves it more because she pays more for rent. She repeatedly brought up the land lord's name as though she is the one that gave my neighbor permission to park here because she pays more in rent. Is it illegal for her to discriminate like this and to share my information with others?
