the dailymail spams any celebrity they can get a picture of. the kardashians live in LA and want to be photographed bc it helps their brand so they are very public with everything they do, hence them being reported on a lot.
there's times when rihanna/bey will be out in the public for like a week and every day their candids will be on dailymail, but than they leave LA or go somewhere more private
Daily Mail is an amazing site. You get an awesome well written article, and then some old hags at the bottom of the page telling you the fault with our stars
