"One Word" is the first and only single from Kelly Osbourne's second album Sleeping in the Nothing. Unlike the pop/punk sound Osbourne sported in the past, "One Word" was a synthpop song that showed Osbourne embracing dance music. The single sounded very reminiscent of the 1980s Visage song "Fade to Grey", which caused some controversy over copyright issues, which was finally settled out of court when Osbourne's writing team agreed to give Visage a share of the royalties.
