Which singer recorded the original “I'm Lovin' It” jingle for McDonald's?

Justin Timberlake recorded the original “I'm Lovin' It” jingle for McDonald's.

Timberlake's recording was part of the campaign's launch in 2003. The song and its recurring “ba da ba ba ba” hook helped give the slogan a musical identity that could be recognized across television commercials and other marketing formats.

The campaign was developed for McDonald's as an international branding effort, and Timberlake's involvement connected the restaurant brand with contemporary pop music. The jingle was not simply a standalone pop release; it was created as part of the advertising campaign.

The vocalist is sometimes confused with other pop stars associated with McDonald's promotions. Timberlake's name is the specific answer for the original recording used in the launch of “I'm Lovin' It.”
