Which singer recorded the original vocal for McDonald’s 2003 “I’m lovin’ it” campaign?

Justin Timberlake recorded the original vocal for McDonald’s 2003 “I’m lovin’ it” campaign.

The campaign used a song connected with Timberlake, and his vocal helped introduce the phrase to a worldwide audience. The advertising rollout began in Germany before the slogan and musical identity spread across McDonald’s markets.

Timberlake’s involvement is often confused with later contributors to the campaign’s music and production. The melody, advertising versions, and credited creative work passed through several collaborators, so the singer is not the same as every person associated with creating or producing the campaign.

The campaign became one of McDonald’s most durable branding efforts because it combined a short slogan, a repeatable melody, and localized commercials. The phrase remained associated with the company long after the original 2003 launch.
