The new single is from her latest album Demi. The video, which Lovato co-directed, is set in a carnival, reported Digital Spy.
The track serves as the follow-up to her recent global hit 'Heart Attack', which reached number three in the UK and ten on the US Hot 100.
Lovato recently revealed that landing her first televison role in 'Barney & Friends' saved her life.
"Even before Barney, I was suicidal. I was 7. With Barney, I guess subliminally, I did have a relationship with this figure that was saving my life in a way.
