Cindy Crawford, who turns 50 in February, is retiring.
Crawford announced her intention in an interview with the United Airlines in-flight magazine Hemispheres this month.

Crawford says her recently released book, Becoming Cindy Crawford, was a way to celebrate her modeling career.
"I’m sure I'll have my picture taken for 10 more years, but not as a model anymore. And that's OK," she said. "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."
While Crawford quit modeling full-time in 2000, she continued to pose professionally, including for last month's stunning Balmain campaign that saw her reunited with her '90s supermodel contemporaries Naomi Campbell and Claudia Schiffer.
Crawford's departure comes just as lookalike daughter Kaia Gerber's own modeling career is beginning to take flight.
The 14-year-old inherited her mother's classic good looks and has already landed her first modeling contract with IMG Models.
In September, Gerber wowed at the Teen Vogue Young Hollywood party, where she rocked Crawford's signature tousled locks and chic style.
Ever the protective mama, Crawford had a few words of wisdom for her rising star daughter.

"Today, models are expected to be so tiny and I worry about that for her, because that was never my natural body type and I don't think it'll be hers either," Crawford told The Edit. "Still, I'll say to her, 'Enjoy carbs while you can!'"
