Singer Demi Lovato has revealed that she had an unpleasant run in with photographers earlier this week and feels bad that she has to bypass meeting fans in order to avoid being yelled at and disrespected by members of the paparazzi.

Writing on her official Twitter page earlier today (June 24), the 'Neon Lights' hitmaker explained that she's sick of this negative treatment:

"When are paparazzi gonna learn? If you're respectful to me, I'll be respectful back. Why does it have to be a war of celebs against paps? Of course if you yell horrible things, I'm not gonna work with you. I'll pose if you are respectful and not being bullies."

"I wanted to stop for my fans today/tonight really bad because I love you so much but I can't deal with how mean those paps are... I always try to stop because I appreciate every single one of you, so if I don't get to you please know I'm sorry and I love you."

The beauty then added that she has to make smart decisions where staying strong is concerned and it often means not putting herself in the firing line of the paparazzi: "Sometimes staying strong means not putting yourself in uncomfortable or triggering situations."
