This features and was co-written by Lovefoxxx from the Brazilian electro-trash band CSS. Frontman Bobby Gillespie told Uncut magazine February 2008 about this collaboration with the singer: "Our voices sound great together. There's three verses I've written, and we got her to write a verse of her own. It's a song about a destructive relationship. That one's not an up, happy song."
Gillespie told The Sun July 11, 2008: "It's just a very honest song about relationships, about a f--ked up love affair. No matter how bad it is, you just go back for more. I think all love affairs are f--ked up."
Gillespie explained to The Sun why they decided to team up with Lovefoxxx: "We love the first CSS album and Lovefoxxx is a really great girl. We asked her to sing on a track before we'd even written it. Her voice is so soulful and sexy."
