Justin Timberlake performed the English-language vocals associated with McDonald's launch of the “I'm Lovin' It” campaign.
McDonald's introduced the campaign internationally in 2003, using the phrase as a global brand platform. Timberlake recorded the song and appeared in promotional material connected with the campaign, giving the slogan a strong pop-music association.
The campaign's music is often attributed to Timberlake as though he wrote every element of it. The production involved several collaborators, including the German group V<bravo and advertising professionals. Timberlake's role was the prominent English-language performer, while the broader campaign developed through multiple versions and markets.
