When Sailor Brinkley-Cook opened up to the world about her issues with body image, it surprised many — including her famous mom, Christie Brinkley. The Dancing With the Stars alum revealed the iconic supermodel “didn’t fully know the pain that [she] was going through” as she got candid about her struggles on Good Morning America.

“I grew up a little bit overweight and I felt the weight of my overweightness on me constantly from people teasing me and people looking at me differently,” the 21-year-old beauty bravely shared on Friday, May 29, revealing being compared to Christie, 66, really “shut down [her] self-esteem.”

Sailor’s virtual visit on GMA comes just days after she opened up about her battle with body dysmorphia and an eating disorder. As she detailed her journey with ABC News correspondent Deborah Roberts, Sailor explained how Christie’s Hollywood career fueled her desire to be even skinnier.

“I was looking up at all these major figures in modeling that are size double zero and they’ve got these thin legs and these tiny waists,” she explained. “I was seeing them being so celebrated by everyone everywhere and being wanted by all the boys and all that greatness that comes around being this tiny supermodel. And I wanted that.”

Because she was comparing herself to others, the up-and-coming actress said she started to look at herself differently. “I have this awful feeling that if I’m not skinny, I’m not worth being celebrated and I’m not worth being praised,” she stressed.

Sailor said her struggles are so bad at times, she’ll just pick apart “the tiniest little things” about her body. “I’ve been just been having these moments where I look in the mirror and I’m just disgusted with myself,” she confessed, especially when it comes to the “little pooch on the bottom of [her] stomach.”

I’m so fucking sick and tired of the photoshop 👏🏼 I’ve been so down on myself recently. Crying about my cellulite, letting the fat on my body ruin my day, getting mad that i’m not as skinny as i once was. The body dysmorphia and left over eating disorder tendencies have been coming in strong. As i come into myself as a young woman my body shifts and changes by the month, the “control” i felt i once had over it has been completely stripped away from me. Hormones, emotions, growing pains. I go on instagram and scroll through photos of girls that look “perfect”.. shiny skin with not a bump to be seen, tiny little waist and thighs that look like chopsticks. And i compare myself, as if how someone on an app on my phone looks should directly correlate to how I feel about my body? What I’ve learned is that I run every day. I go to the gym 6 times a week. I fuel my body with beautiful food. I am so fucking LUCKY to have two legs and a healthy body that takes me through life. I’m so tired of thinking anything that makes up ME is something to be ashamed of. So as most 21st century girls would do, I’m putting this out there on instagram. Declaring that I have cellulite, and a stomach that doesn’t always look “pleasant” (whatever the fuck that means) and I am 100% imperfect human. And I’m proud as hell of my body! If you’re out there hating on yourself, stop!! Appreciate yourself. You’re body is so magical. That’s all. Have a nice day. 😌

The stunning TV personality first opened up about her issues with self-image as she uploaded a lengthy post via Instagram on May 24. Alongside three photos of her wearing a white bikini, Sailor explained she’s been “so down” on herself as of late.

“Crying about my cellulite, letting the fat on my body ruin my day, getting mad that I’m not as skinny as I once was,” she penned at the time. “The body dysmorphia and leftover eating disorder tendencies have been coming in strong.”

Sailor said as she grows into “a young woman,” she’s noticed shifts and changes in her body. “The ‘control’ I felt I once had over it has been completely stripped away from me,” she stated. “Hormones, emotions, growing pains.”

However, Sailor insisted she’s doing her best to overcome the daily battle. “I am so f—king LUCKY to have two legs and a healthy body that takes me through life,” she gushed at the end of her post. “I’m so tired of thinking anything that makes up ME is something to be ashamed of.”

Sailor is so beautiful inside and out!
