Which singer appeared in the original 2003 “I'm Lovin' It” promotional music video for McDonald's?

Justin Timberlake appeared in the original 2003 “I'm Lovin' It” promotional music video for McDonald's.

The campaign connected McDonald's advertising with contemporary pop music and youth culture. Timberlake was featured in the video for the song associated with the campaign, while the phrase itself became the company's global slogan. This helped the branding effort feel more like a music-driven cultural campaign than a conventional restaurant advertisement.

The campaign's music credits are sometimes simplified or confused. Pharrell Williams was involved in producing and writing the associated material, while Pusha T has also been connected to the creation of the jingle. Timberlake's role was as the featured performer in the promotional video, not as the sole creator of the campaign.
