It seems that Kaia has inherited her mother's supermodel genes, wearing her long brunette locks down in tumbling waves, and posing for the camera.
Within hours of the photo appearing on Instagram, plenty of fans took to leaving comments, speculating that Kaia's striking beauty could see her becoming a Victoria's Secret angel one day.
It's not the first time that Kaia has caught the fashion pack's attention – the young model wowed when she shared a photo of herself earlier this year wearing several of Cindy's old clothes, including a particularly striking floral Roberto Cavalli dress.
Cindy herself has revealed that she feels social media has become a powerful tool for models breaking into the industry.

"Because of social media, so many of the girls today, like Coco Rocha, Lily Aldridge, Georgia May Jagger and Cara Delevingne, are brand-building," she explained. "When I started modelling there was no language for that."
"I think that things have changed certainly because of America's Next Top Model and Instagrams and selfies," she added.
