The Real Story Behind the 3 Most Iconic Words In Pop History: 'It's Britney, Bitch'

With the release of the first single, "Gimme More," made one phrase -- "It's Britney, bitch" -- instantly iconic, but according to one of the men behind the music, it actually began as "an inside joke."

Nate "Danja" Hills, who helped write "Gimme More" and four other tracks on "Blackout," told E! News he "had no idea that [those three words] would become kind of the marquee statement for the entire album, like the theme of the album and that time period and that moment in her career."

"We were in the studio recording, and Jim Beanz, the co-writer and vocal producer, was like, 'Can you say 'It's Britney, bitch?'' It was some little inside joke happening in the studio, and he just got her to say it. I was shocked that she said it, and we kept doing the record," he added.

Even though "Blackout" was Brit's first studio album to not debut at No. 1, it still remains one of her most beloved.

"'Blackout' was the first time I worked with Hills, and he gave me the opportunity and freedom to work with more urban sounds and influences," Spears told The Fader earlier this month. "It really inspired me! I also got the chance to sing more and stretch my voice in ways I hadn't done before. The magic of 'Blackout' was actually pretty simple. It just wasn't so thought out. I just did what I felt and it worked. Sometimes less is more I guess."
