Christie Brinkley was Billy Joel's "Uptown Girl." Cindy Crawford, Naomi Campbell, Linda Evangelista and Christy Turlington helped George Michael declare his "Freedom." And Helena Christensen played Chris Isaak's "Wicked Game," as directed by the legendary Herb Ritts. Models have been appearing in music videos nearly as long as the form has been alive, lest we forget Calvin Klein brief-fillers  Djimon Hounsou and Antonio Sabato, Jr. in Janet Jackson's "Love Will Never Do (Without You)," also directed by Ritts. So in honor of our May month of music, Male Model Humpday takes a look at the hunky men making beautiful music...videos.
