Iconic '90s supermodel Cindy Crawford to retire at 50.

What defined the ’90s for you? Maybe it was baggy jumpers, Doc Martens or Nirvana releasing ‘Smells Like Teen Spirit’.

Or maybe it was the cult of the supermodel.

Cindy Crawford, Kate Moss, Claudia Schiffer, Naomi Campbell, Linda Evangelista, and Christy Turlington, also known as ‘the Big Six’ or, #SquadGoals, as they would be known now. They were on the cover of every magazine, in every Pepsi commercial, in music videos and became some of the most recognised faces, and bodies, in the world.

Today, thirty years after her first cover of Vogue, reports say Crawford will retire on February 20 - her 50th birthday.

“I’ve done it. I’ve worked with all these incredible photographers. What else do I need to do? I can’t keep reinventing myself. I shouldn’t have to keep proving myself. I don’t want to,” Crawford told Rhapsody magazine.

“I’m sure I’ll have my picture taken for 10 more years, but not as a model anymore."

In 1995, Crawford was named the highest-earning model in the world by Forbes, the same year she divorced from husband of four years, Richard Gere.

Crawford married fellow model Randy Gerber in 1998 and the couple have two children, Presley and Kaia, who, as a 14-year-old Crawford mini-me and budding model.

In an interview with The Thick, Crawford told Kaia, 'Your dad and I want you to be happy - whatever that may mean - so if modeling is something you like and want to continue, I can provide a road map and help you make good choices.'

As for the future of modelling, Crawford says the 'Gigis, the Karlie's and the Cara's' are where we're headed. Crawford told Allure magazine, "For a while, a lot of the models looked the same. Now they're all over the map again, which I think is interesting for people, and we feel like we know them and their personalities."
