Photographer Mario Testino once snapped a photo of model Kate Moss in towel after a shower and posted it to Instagram. Little did he realize at the time that a "private club" was forming. Testing now has an ongoing series of pretty famous people wearing nothing but a towel, hence, the "Towel Series." For his latest, Cody Simpson is snuggly wrapped around Gigi Hadid, a classic Kendall Jenner, a relaxed Ansel Elgort and a hard-bodied, abs-blessed Justin Bieber all pose for the acclaimed fashion photographer in their towel. Must be charmed life to be Testino!
