Which singer was featured on the original “I'm Lovin' It” recording used by McDonald's?

Justin Timberlake was featured on the original “I'm Lovin' It” recording used by McDonald's.

The recording was part of the campaign that McDonald's introduced internationally in 2003. Timberlake's involvement connected the advertising platform with contemporary pop music and helped make the short musical hook recognizable beyond the restaurant's conventional commercials.

The campaign's jingle was produced with contributions from several music professionals, and the songwriting credits are sometimes simplified in popular retellings. That is why the singer's role and the broader creation of the jingle should be distinguished.

The phrase itself became more important than any one recording. McDonald's adapted the campaign across countries and advertising formats, keeping the slogan and melodic identity while changing imagery, performers, and local execution.
