The 49-year-old beauty is calling time on her career - which has lasted for over 20 years - and stepping away from the camera after she turns 50 on February 20 because she doesn't want to keep "proving" herself, reported E!Online.
Crawford, who quit full-time modelling in 2000, said, "I'm sure I'll have my picture taken for 10 more years, but not as a model anymore. And that's OK. 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."
