Which singer performed the English-language version of McDonald’s 2003 “I’m Lovin’ It” song?

Justin Timberlake performed the English-language version of the song used in McDonald’s 2003 “I’m Lovin’ It” campaign.

The campaign marked a major effort to give McDonald’s a single global identity. The phrase appeared in advertising across many countries, while local markets adapted the commercials and language for their audiences. Timberlake’s recording helped turn the campaign’s musical hook into a widely recognizable part of the brand.

The song’s creative history is sometimes simplified. Pharrell Williams was involved in the campaign’s music and production, but Justin Timberlake was the featured singer on the English-language recording associated with the advertisements.

“I’m Lovin’ It” became one of McDonald’s longest-running modern brand lines. Its combination of a short phrase, pop music, and international adaptation helped move McDonald’s advertising beyond individual product promotions.
