Which singer was featured on the song connected with McDonald’s “I’m Lovin’ It” campaign?

Justin Timberlake was featured on the song connected with McDonald’s “I’m Lovin’ It” campaign.

The campaign launched in 2003 and used a pop-oriented musical identity rather than relying only on a spoken advertising slogan. Timberlake recorded a version of the song associated with the campaign, helping connect McDonald’s branding with contemporary popular music.

The campaign’s famous short musical phrase was developed through a broader collaboration involving advertising agencies, producers, and musicians. Pharrell Williams was also involved in the project, which is why accounts of the campaign may mention several different music-industry figures.

Timberlake’s role is sometimes overstated as if he created the entire campaign or its slogan alone. The branding was a collaborative advertising project; his specific connection was performing the song version used alongside the McDonald’s platform.
