2. She knows that the best anti-aging secret is... hair extensions. "I think of it as a choice. Do I want to put in the time or do I just want to put in the hair? Literally, it's just click, click, click ," Brinkley revealed to HuffPost Style.

3. She doesn't believe in crash diets or bogus eating habits. (Amen!) Brinkley explained to Prevention, "Go ahead and have the Kit Kat at the movies. If you don't satisfy an urge sometimes, you often substitute less-satisfying things and end up eating more."
