Older siblings: Poppy Delevingne and Chloe Delevingne
The Delevingne sisters are both rooted in the fashion world, but little sister Cara is on a roll when it comes to making headlines. Yes, Poppy lives a more low-maintenance lifestyle with her husband, James Cook, and though she attends the occasional music festival or award ceremony, she's best known for her preppy, polished London style and status as a Fashion Week fixture — in fact, she often pops up in the front row to support her little sister as she stomps the catwalk for Chanel, YSL, and Burberry.
Cara, on the other hand, is undoubtedly the wild child; not only has she surrounded herself with a bevy of fun-loving celebrities like Rihanna, Kate Moss, Suki Waterhouse, and Kendall Jenner, but she's also become something of a social media star thanks to her goofy snaps and penchant for flashing her boobs. She made waves last year when she dated actress Michelle Rodriguez and isn't afraid to stir up trouble with graphic message t-shirts or flipping the bird at photographers. Cara is the ultimate cool little sister, what with her "girls just want to have fun" attitude and "life of the party" personality.
