Christie Brinkley looks amazing for someone in their 20's...and she's in her 60's!
"This is a real full circle moment for me," @christiebrinkley said through tears on set. "I can get very emotional about this. How many years ago, I was that insecure girl hoping that I would be good enough for the magazine. So to see my daughters now having the same thoughts I had, and to be able to see them actually be there on the job, was definitely a big moment."
