A time-travelling Katy Perry

David LaChapelle is well known for his saturated, glamorous, often dream-like photography... So could there be a more perfect subject for his lens than popette Katy Perry? Shooting a campaign for hair styling brand ghd meant there was always going to be some element of fantasy involved, and LaChapelle doesn't disappoint. Katy is a kind of uber-glamorous modern day Sleeping Beauty, waking up in three different iconic eras of style: 50s glamour, 70s boho chic and 80s new wave (with hair styled, of course, to match).
