All grown up!
Christie Brinkley's youngest daughter Sailor Brinkley Cook took to Instagram on Feb. 9 to celebrate #ThrowbackThursday with an adorable childhood snap.
The 18-year-old, who recently came clean about her struggle with body image, captioned the pic, "#StayHumble." She received overwhelming support from fans after sharing the photo, with one follower writing, "Thanks for posting this, you are beautiful!"
In an interview with People magazine, Sailor revealed that it wasn't easy being raised by a supermodel mom. "I grew up looking at these photos of my mom, never thinking that I would ever be able to do that," she said. "To be compared to my mother who has this extremely successful career under her belt when I’m just getting started? I’m not trying to be her. But I’m fine. I don’t get hurt by this stuff."
Despite her insecurities, the blonde beauty is following in her mom's footsteps. Most recently, she posed alongside the 63-year-old and her half sister, Alexa Ray Joel, for a sexy spread in Sports Illustrated's Swimsuit Issue.
