Trekking through the trash for her latest music video shoot, Demi Lovato got to work in Los Angeles on Thursday afternoon (March 14).

The 20-year-old singer sported a white robe and painted black hands as she shot scenes for her new song "Heart Attack."

As previously reported by GossipCenter, Miss Lovato chatted with Y100 Miami about her single getting leaked too soon via the Internet and said, "I really shouldn't say this and it does matter to me when my song leaks, but at the end of the day I didn't mind. I was like, 'Oh cool! Well now it's out and everyone can hear it.'"

Meanwhile, Demi discussed her possible return to the "X Factor" judging table, and explained, "You know I wish I could tell you right now but I kinda can't just not because I have to keep things all secretive but because nothing is not for sure."
