Which singer performed the English vocal on McDonald’s 2003 “I’m Lovin’ It” campaign track?

Justin Timberlake performed the English vocal on McDonald’s 2003 “I’m Lovin’ It” campaign track.

The campaign was launched internationally in 2003 and used the phrase “I’m Lovin’ It” as a central piece of McDonald’s branding. Timberlake appeared on the English-language recording associated with the campaign, while the production involved the German music group Jung von Matt and producer Pharrell Williams.

A frequent mix-up is treating the song and the slogan as exactly the same thing. The slogan became a long-running brand line, while the recorded track was a musical advertising component used to support that campaign. McDonald’s adapted the campaign across markets and languages.

Timberlake’s participation connected the fast-food brand with contemporary pop music and helped the campaign travel beyond a conventional spoken commercial. The phrase then became one of McDonald’s most durable modern identity elements.
