Demi Lovato, what's going on here?
The 20-year-old singer was snapped on the set of her "Heart Attack" music video Thursday in Los Angeles. While her hair and makeup were super glam, her hands and wrists were completely covered in black paint and she was walking through piles of trash!
The X Factor judge, wearing a white robe in between takes, looked focused on not messing up her hands as she made her way past a graffiti-covered dumpster.
