Demi Lovato recently graced the cover of Seventeen Magazine's August 2014 issue where she did not only rock rainbow-colored hair, but also talked about getting into rehab, fame and more.

Lovato confessed that despite going to rehab and receiving the finest care possible, there were still instances where the "Neon Lights" singer didn't feel her best.

"Since I went to treatment, there have been days when it's felt really easy, and I've felt great about where I am. But then I have moments when it's not. That's life. You can't just take your mind and your body into the shop and get it fixed. It doesn't come out repaired. It's not like a car. It takes time - pace yourself. Every day is a new opportunity to change your life and be who you want to be," she said.

The "Heart Attack" singer also confessed that she can most likely live without the glitz and the glamour of the showbiz industry, according to Beauty World News.

"When I give back, I don't question my self-worth. I know that if my career were to fall apart tomorrow - even if I were never to have money or fame again - I'd still have value in my soul, because I know that I can have an effect on someone else's life,"

Meanwhile, Lovato has slammed the paparazzi via Twitter on Monday night after the "Frozen" singer didn't have the chance to meet her fans because the photographers were acting very mean to her, MTV reported.

"When are the paparazzi gonna learn? If you're respectful to me, I'll respect you back. Why does it have to be war of celebs against paps?"

In another tweet, she wrote, "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."

Lovato addressed her fans as well and wrote, "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..."
