Which singer recorded the original English “I'm Lovin' It” campaign song for McDonald's?

Justin Timberlake recorded the original English “I'm Lovin' It” campaign song for McDonald's.

The song was part of McDonald's global branding campaign launched in 2003. Timberlake's recording helped give the advertising platform a contemporary pop sound, while the short musical hook became the campaign's most recognizable audio feature.

The campaign was not simply a conventional artist endorsement. The phrase and advertising concept were developed for McDonald's, and the company adapted the campaign across markets and media. Timberlake's association with the recording nevertheless made his contribution an important part of the campaign's early public identity.

A common misunderstanding is that Timberlake originated every version of the slogan or performed every international adaptation. McDonald's used localized executions in different countries, but Timberlake is specifically credited with recording the original English campaign song.
