Christie must have had the ladies in awe with that amazingly smooth, unlined skin that bore no trace of the usual signs of aging.

The mother-of-three was seen giving her mirror reflection a humorous wide-eyed look while pulling a strand of hair.

The stunner boasted that she was wearing no make-up at all, just a slick of moisturizer and eye serum from her own line of skincare.

'Getting ready to appear on HSN,' Christie shared, adding: 'The only thing I have on my skin is my Recapture Day Cream and Refocus Eye Serum.

'This is my first step everyday routine before applying make up. I personally recommend trying it for yourself. If you start now in just 4 weeks you will see smoother, firmer, younger looking skin in time for Thanksgiving!'

'Thank you @sandylinter for getting me ready for the 2Am TV Spot on @hsn with your fabulous artistry! And @mitchbarry im living my simple chic natural look you created! I can't wait to share my beauty secrets with my friends at home !

Even with the addition of smoky eye shadow and lip gloss, there wasn't much of a transformation, which is a compliment to the former Sports Illustrated Swimsuit cover girl.

She concluded by sharing an on-set photo of herself in black trousers and a bright pink blouse, standing in front of her logo.

'RESULTS worth cheering about! With Christie Brinkley Authentic Skincare!' Christie began.

'On the set @hsn last night at 2:00AM with my lovely fun and funny hostess @theofficialhelenkeaney thank you for for staying up late with us!'

Cover up in Christie's Saint Laurent coat for winter

It's coat season!!!!!!

Time to celebrate with an excuse to treat yourself to a super luxe and expensive coat.

But really though, we'll never feel guilty about spending a lot of money on essentials: purse, shoes, coats -- these are the areas you SHOULD splurge.

Because first, there's no price tag on staying warm during the darkest of winter days and second, a really beautiful coat like this one will last you a lifetime.

And Saint Laurent has really outdone itself with this one. The cut and tailoring on Christie is super sharp, and we're keen on the double-breasted buttons.

Like Christie, you can throw this over a casual outfit and voila! You've got the perfect ensemble.

So click right to buy Christie's coat from MatchesFashion -- though with fair warning you should be prepared to part with $4590.

That being said, we've culled together a few options in our edit below that'll pack the same style punch without breaking the bank.

She added with another shameless plug: 'I hope you ordered your beauty sleep so you wake up looking like a star! ill be back today at 4:00 and 7:00.'

Christie's love life seems to be going smoothly too as her new romance with 64-year-old rocker John Mellencamp heats up.

The couple, who were first linked in September, have been spotted on several cosy outings since then in New York City.

Even Christie's ex Billy Joel, 66, joked about it during a September 29 concert in the Big Apple after he performed The Longest Time, which he wrote for Brinkley.

'And now she's dating John Mellencamp,' Billy, 66, told fans at Madison Square Garden.
