40 Photos of Celebrities With Their Lookalike Sisters

Anyone with a sister can relate to that question: "Are you so-and-so's sister?!?" When you're famous (or your sibling is), it may get a little old. But we doubt these lookalike siblings get asked it very often—their nearly identical looks say enough. From siblings who are both in the industry to stars and their non-famous fam members you didn't even know existed, see who made our list of lookalike sisters.

While they may look nearly identical now, Nicky dyed her hair brown in the early 2000s, around the peak of her older sister's fame. They also live very different lifestyles: Paris is a socialite, reality star, and DJ, while Nicky works in fashion and is married with two children.

Not only does Gisele Bündchen have a twin sister, Patricia (right), but their younger sister, Rafaela (left), looks like she could be their triplet. The siblings attended an event together in 2007, and their matching beach waves and sun-kissed skin made it more than clear that they were related.
