Which singer appeared in an early McDonald’s “I’m Lovin’ It” campaign advertisement?

Justin Timberlake appeared in an early McDonald’s “I’m Lovin’ It” campaign advertisement.

McDonald’s launched the “I’m Lovin’ It” campaign in 2003, and Timberlake featured in an early advertisement connected with the campaign. His appearance helped link the restaurant’s new brand platform to contemporary pop culture and music.

The campaign’s signature phrase and musical identity are sometimes attributed entirely to Timberlake, but his role was as a performer in the advertising campaign rather than the sole creator of the brand. The campaign involved agencies, musicians, and market-specific production.

The advertisement was part of McDonald’s effort to modernize its public image while keeping the Golden Arches recognizable. The campaign eventually became global, with localized executions appearing in different languages and cultural settings. Timberlake’s involvement is therefore a notable early association, not the definition of the entire campaign.
