Who performed the English-language vocal version of McDonald’s 2003 “I'm Lovin' It” jingle?

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

The campaign began internationally in 2003 and used the phrase as a major element of McDonald’s global branding. Timberlake’s vocal performance helped turn the short advertising tune into a widely recognizable piece of commercial music. The campaign was connected to work by musician and producer Pharrell Williams, which is why the two names are sometimes confused.

Timberlake’s role was performance, not ownership of every creative element associated with the campaign. Pharrell Williams was involved in writing and producing the jingle, while the advertising campaign itself was developed through McDonald’s agencies and adapted for different markets.

The campaign’s music and slogan should also be distinguished from the later use of “I’m Lovin’ It” as a broad global tagline. The vocal recording is one specific part of the campaign’s branding history.
