Supermodel Cindy Crawford, who will turn 50 this month, may be getting ready to "move on" from modelling.

She has suggested that retirement may be quickly approaching, reports eonline.com.

"I feel like I'm allowing that to have been great, and I'm celebrating it. And I'm sure I'll have my picture taken for 10 more years, but not as a model anymore. And that's okay," she was quoted as saying by United Airlines' Rhapsody magazine.

"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," she added.

For the past several months, Crawford has been hard at work supporting her book "Becoming Cindy Crawford". In her latest interview, she admits that the work was a way to bid farewell to her days as a model.

"Maybe not say goodbye," she explained, "but move on".
