Which artist sang on the 2003 recording of McDonald's “I'm Lovin' It” jingle?

Justin Timberlake sang on the 2003 recording used for McDonald's “I'm Lovin' It” campaign.

The campaign began internationally in 2003 and used a pop-oriented song associated with Timberlake. The “ba da ba ba ba” vocal hook became one of the most recognizable sounds in McDonald's modern advertising, while “I'm Lovin' It” became the company's global slogan.

The campaign had several creative contributors. German advertising agency Heye & Partner developed the original campaign concept, and the music was connected to producer and songwriter collaborations. Timberlake's participation helped give the campaign a contemporary pop-culture profile.

The singer is sometimes confused with the songwriters and producers involved in the recording. Timberlake was the featured performing artist associated with the released track, not the sole creator of the entire campaign or slogan.
