In McDonald's branding history, which singer appeared in the early music video for “I'm Lovin' It”?

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

The campaign's music was connected to Timberlake, who appeared in a promotional video associated with the launch. The advertising phrase and its musical hook were then adapted for McDonald's international marketing, making the campaign one of the company's most durable modern brand platforms.

Timberlake's appearance can cause confusion because the campaign was not simply a traditional artist endorsement. Multiple agencies, producers, and musical contributors were involved in developing the work. McDonald's used the song and slogan as corporate branding across markets, while Timberlake's video appearance gave the launch a strong pop-culture connection.
