Apart from polititians what are some popular Polish singers, actors, models (modelki) on the covers of magazines
I am afraid no members here are interested in such things. We prefer to focus on a really serious stuff and to run deep intellectual discussions on history, philosophy, education, science, economy etc.
My advice is: goggle the name of a magazine you like with the word: okładki which means covers. Then you will be able to see them all grouped together.
E.g.,
