The 43-year-old model feels that industry grew because of the contributions made by renewed gay designers like Gianni Versace and Alexander McQueen, reported Contactmusic.
"The gay community has made an incredibly profound impact on the fashion industry, and without key creative such as Marc Jacobs, Gianni Versace, Dolce & Gabbana, Alexander McQueen, to name a few, the art form would not be so vibrant," Campbell said.
"Gay culture and fashion go hand-in-hand in that they flourish in the light of making bold and brave statements," she added.
