This song seems to allude to Sheryl Crow's called-off engagement to champion cyclist Lance Armstrong. Crow refused to confirm this in an interview with Rolling Stone magazine saying: "All I can say is that I've been engaged 3 times. So I have a thing about diamonds!"
Lily Allen wrote "Something's Not Right" for the soundtrack of the Peter Pan prequel, Pan. The song was inspired by the heartache that Allen experienced after suffering a miscarriage when she was six months pregnant with her first child by husband Sam Cooper in 2010.
