Demi Lovato has made no secret of her horrifying past at the hands of bullies and how it led to her developing an eating disorder and cutting herself.
But now The X Factor judge is putting her experience to great use by partnering with Secret to be the ambassador of their new "Mean Stinks" anti-bullying campaign to help others going through similar issues.
"I had a really tough time when I was in middle school," the 20-year-old performer told People.
"People would write 'hate petitions' about me and send them around to be signed. They'd have CD-bashing parties of my demos. They'd come to my house, stand across the street and yell things. It was a very emotional time for me, and all I wanted to do was get away.
"Back then, there were times I didn't think I'd be able to move on."
The "Mean Stinks" campaign is encouraging girls to "gang up for good" and Demi inspired students at New York City's Young Women's Leadership School on Thursday to have a "Drama Free School Year" by making them swear to stay out of trouble and to share the anti-bullying message by wearing blue nail polish on their pinky fingers.
"I'll definitely be wearing the nail polish starting soon," Demi shared. "It's a conversation starter: 'Hey, why is your pinky blue?' 'This is a pinky promise that I'm not going to bully people, that me and my friends are ganging up for good.'"
Secret is donating $1 from every Mean Stinks Clinical Strength deodorant sold to help the cause.
