Who performed the vocal version of McDonald’s “I’m lovin’ it” jingle used in the 2003 campaign?

Justin Timberlake performed the vocal version of McDonald’s “I’m lovin’ it” jingle used in the 2003 campaign.

McDonald’s introduced “I’m lovin’ it” in 2003 as a global brand campaign and slogan. The campaign used a short, highly repetitive musical hook designed to work across television, radio, and international advertising. Timberlake recorded a vocal version of the song, helping connect the campaign with contemporary pop culture.

The campaign’s credits are sometimes simplified. Pharrell Williams was involved in writing and production, while the German agency Heye & Partner developed the campaign concept. Timberlake’s vocal performance is therefore distinct from the people credited with creating or producing the jingle.

“I’m lovin’ it” became one of McDonald’s longest-running global slogans. It replaced a series of market-specific advertising lines with a phrase intended to be recognizable across many countries and languages.
