Sailor Brinkley Cook is not having it when it comes to internet haters.

The 18-year-old model daughter of Christie Brinkley flaunted a Sports Illustrated pic of herself in nothing but a thong and a tank top on Sunday, Photoshopping in close-ups of her booty. The post was in response to someone reporting the original picture to Instagram, and flagging it as inappropriate content.

"Apparently Instagram isn't the biggest fan of my little bum and I have been deleted and reported," she wrote. "To that I say LET THEM SEE CAKE!!!!!!!! @si_swimsuit."

This isn't the first time Sailor has called out the haters. This past August, she shot back at those comparing her looks to her famous mother.

"Believe it or not I am my own person with my own beliefs and own thoughts and my own face!" she Instagrammed. "Yes I am so fortunate that my mother is my mother... And she will always be an inspiration to me... But being constantly compared to her 50+ years of success at only 18 years old? And being told I could never amount to what she was and what she looks like? Doesn't feel great."

"I'm just a person figuring out what I want to do and what makes me happy. Leave me alone," she added. "Let's just f***in spread love you guys. And pleaseeeee stop trolling me."

These days, it appears Sailor is more confident than ever. Last month, the blonde stunner proudly posed in a bikini for a sexy Sports Illustrated photo shoot featuring both her mother and her older sister, 31-year-old Alexa Ray Joel.

"I am healthy, I treat myself well, and for that I'm happy," she wrote on Instagram alongside a gorgeous shot of the trio. "I've looked in the mirror and been able to LOVE the things about my body that beauty norms deem 'undesirable.' I now have grown to know that my body is worthy of so many great things. I don't need to be a size 0 to believe in myself."
