Beyoncé told the writer Dennis Hensley about this tune. She explained: "The song talks about how, when you're falling in love, you do things that are out of character and you don't really care because you're just open. The song came from me actually looking crazy one day in the studio." Beyoncé added: "I said, 'I'm lookin' crazy right now,' and Rich Harrison, the producer, was like, 'That's the song!'"
