"Please remember that it is so important to not care what other people think unless you truly value there opinion, it only gets in the way," Delevingne tweeted.
"Also you have no idea how valuable privacy is until you loose it!!!" she added.
The 21-year-old model went on to call paparazzi "assassins" and praised Paris, for being the only city that forbids photographers from stalking celebrities for their picture.
"It's horrible!! How many people have to get hurt or even killed to realise that it's not right?," she said of the incidents caused by paparazzi. "It actually took someone losing there life! Diana, an inspirational woman and then it changed but they still won't change it in London!" she added.
"It scares me because they act like they're assassins with there telescope lenses, hiding in bushes or whatever they can find," she continued. "Ha I actually used to feel so sorry for them, how boring it must be to follow people around all the time but some of them actually enjoy it," she wrote.
Delevingne later pointed out that she was done with her rant, and left her fans to ponder an interesting question.
