Which musician appeared in the early promotional video for McDonald’s “I’m Lovin’ It” campaign?

Justin Timberlake appeared in the early promotional video for McDonald’s “I’m Lovin’ It” campaign.

McDonald’s launched the global “I’m Lovin’ It” campaign in 2003. Timberlake was featured in a promotional music video connected with the campaign, giving the slogan a prominent pop-music association during its introduction.

The campaign was not simply a celebrity endorsement. Its central asset was the short slogan and musical hook, which McDonald’s adapted across international advertising. Timberlake’s appearance helped the launch reach audiences beyond conventional restaurant commercials.

The campaign is also associated with the production team behind the “I’m Lovin’ It” song and its widely repeated musical phrase. Timberlake’s role should not be confused with claims that he wrote the entire campaign or served as its sole creator.
