Which singer performed the English-language vocals on McDonald's 2003 “I'm Lovin' It” jingle?

Justin Timberlake performed the English-language vocals on McDonald’s 2003 “I’m Lovin’ It” jingle.

The campaign introduced the phrase that became one of McDonald’s most recognizable modern branding lines. Timberlake’s recording helped give the advertising music a pop-oriented profile, connecting the global fast-food brand with contemporary music culture.

The campaign was developed through work involving the German agency Heye & Partner, the advertising network DDB, and producer and songwriter collaborators. The phrase was adapted for use in multiple markets and languages, so international versions do not always feature identical vocals or wording.

A common mix-up is to credit Timberlake as the campaign’s sole creator. He was the featured vocalist on the English-language jingle, while the broader campaign involved agencies, producers, and other musicians.
