Christie Brinkley Amazes At 60: Push-Ups, Peanut Butter + Fuji Apples

Christie Brinkley can't wipe that huge smile off her face these days.

And who would blame her? When you've turned 60 and defy gravity, and all those nasty things that come with natural aging,  well, then she has a right to show off and grin.

Yeah, she's been playing coy with the camera + striking pose after pose, but wouldn't we all?

So, what is Christie Brinkley's beauty secret?

To top it all, it is merely great DNA. She is just super good-looking with excellent facial symmetry.

The rest of it?

Christie leads a clean, active lifestyle.

Plus....there are the push-ups, peanut butter and Fuji apples.

Those are key.

The beautiful blonde and mom-of-3 keeps fit the old-fashioned way:

"I try to get in 100 push-ups every day," said Christie. "It's really easy. I keep a rolled up yoga mat under my bed. I'll do 30 push-ups before I get in the shower. Then I do another 20 before I dry my hair, and now I've done 50. After I dry my hair, I'll come back and I'll do more."

The vegetarian beauty also LOVES to snack on Fuji apples with peanut butter.

Here's the iconic model about a month ago. Watch it here on YouTube.

Sigh....If only it were that easy.....
