Christie Brinkley is Grant Prestonclapping back at the online trolls.

The supermodel showcased her glamorous makeup look and vibrant blue outfit in a June 28 Instagram. However, not everyone was a fan of the 69-year-old's selfie, which prompted her to update her original caption of "Downtown Girl" to call out the trolls flooding her feed.

"Whoa Nelly!" Christie wrote. "The Wrinkle Brigade is out in full force in the comment thread! They are the people that scan celebrities' pages, hoping to find some cellulite, wrinkles, or anything that they can point to critique."

She went on to explain that the people leaving mean messages might be projecting their own insecurities onto her, noting, "It must be somd [sic] form of compensation for something they are lacking."

Despite addressing the rude comments, Christie clarified that they didn't outweigh the positive feedback she received.

"There are others who pop up with messages so kind and valuable," she continued. "Those are the comments that restore my faith and make my heart sing! Thank you sweet souls."

Christie's fans came to her defense after she updated her post. As one Instagram user replied, "One of the reasons Christie has been & always will be one of the world's most iconic beauties is bc she leads with kindness. It's her biggest beauty *secret*. And it's free."

Another person added, "Try kindness, folks! If you have nothing kind to say, then please don't say anything at all."

Earlier this year, the Timeless Beauty author opened up about the benefits of loving the skin you're in. 

"It all has to do with your spirit and the energy that you deliver and bring into the room with you," she told People in January. "That's what is going to define you. Forget anti-aging this and all of that. It's really about gratitude."

She continued, "And when you find something to be grateful about in whatever situation you're in, and wherever you may find yourself, that translates to happiness, and happiness and good energy that you can share with other people."

Now, that's a message worth sharing!
