Christie Brinkley, Now
Now that the supermodel is 65, she’s focused on being a mom and entrepreneur, though she still hits the runway every now and then.

Brinkley credits her vegetarian diet for her ageless look. “I am a life-long vegetarian, so my diet is really, really good and I think your attitude plays a huge role too,” she told Fox News.
