Christie Brinkley certainly has amazing genes to be looking this fabulous at 56, however a few red flags point to the help of plastic surgery.
For starters, i don't think there is any debate whatsoever regarding her breast implants.
But the real mystery is Christie's face and whether or not its seen the inside of a plastic surgeons office. The red flag i alluded to earlier is the expressions or lack thereof, coming from the forehead region of Ms. Brinkley.
This could be the result of a full blown brow lift or perhaps frequent botox injections. I guess this is kinda like a plastic surgery mystery of sorts.
