This is the second single from American pop singer Demi Lovato's sophomore album, Here We Go Again.

The song was written by Lovato together with Jonas Brothers producer John Fields and Anne Preven, who co-wrote Natalie Imbruglia's hit single, Torn.

Demi told MTV News that the song is meant for all the girls out there who need to remind men that they messed up. However, she refused to say just who the unlucky guy is at the center of the song. "I love this song for many reasons," the Disney singer/actress said. "It had a different sound than a lot of my songs. I related to it personally more than other songs, and I have so much fun with it. I thought if it could be a single that it would be incredible to perform it all the time."

The promo was filmed on October 26, 2009. Lovato told MTV News about it: "The music video relates to the song in a way that a girl has so much to say to the guy, and it feels like he's not listening, and she wants him to remember everything that they had. And so instead of having a love interest in this video, it's all about being fierce and kind of, like, taking control as a girl. It's like girl empowerment. Yeah, divas!"
