McD’s ‘I’m lovin’ it’ breaks in U.S.

McDonald’s this week launches the U.S. portion of its global “I’m lovin’ it” ad campaign with five spots from Omnicom Group’s Heye & Partner in Unterhaching, Germany. The spots employ a hip-hop jingle with vocals from The Clips and Justin Timberlake, who makes a cameo in one spot airing around the world. Also, pro skateboarder Tony Hawk stars in a spot breaking Friday for the Oak Brook, Ill., company’s Mighty Kids Meal. That ad is from Publicis Groupe agency Leo Burnett here.
