Twenty years ago, George Michael released the video for his song "Freedom! '90." (Check out the video if you need a refresher.) Catchy but also deep in the way it reveals much about Michael's struggles as an artist and a then-closeted gay man, the track stands on it own. But Michael wisely made "Freedom! '90" a bigger hit by casting the supermodels of 1990 in the video, lip-syncing the song. In honor of the 20th anniversary, we thought we'd take a look at how the past two decades have treated Cindy Crawford, Naomi Campbell, Linda Evangelista, Christy Turlington and Tatjana Patitz as well as Michael Himself.
