We love our siblings, even when they drive us totally crazy. Sibling relationships are fascinating, though, whether we're very close or struggle to feel connected. That's because while our DNA might be the same, we can be shockingly similar to our siblings or completely different people in just about every way imaginable. Sometimes, it's hard to believe we even came from the same family at all, but the love is always there.
Still, siblings usually resemble one another a least a little bit so it's hard to deny that we're related no matter what direction we go in life. And in some cases, even if we're years apart in age, we look almost identical. That's true for celebrity siblings, too. Some of our favorite famous singers, actors, and other Hollywood stars look so much like their older or younger siblings, it's actually pretty freaky.
Dakota and Elle Fanning
Dakota used to be the only famous Fanning sibling we knew of. However, her sister Elle is quite an accomplished actress, too. As we've watched them both grow up on-screen in recent years, it's hard to deny that they look more and more alike all the time!
Gigi and Bella Hadid
Bella and Gigi Hadid are two of the most famous supermodels of our time. But they are also lookalike sisters. They have quickly become some of the most iconic trendsetters out there, as far as fashion goes. We've come to know their faces pretty well by now, but the truth is, we can barely tell them apart!
Chris and Liam Hemsworth
These Australian brothers definitely have the acting chops. They also have striking good looks, which probably makes them OK with looking so much alike. Chris and Liam actually have an older brother named Luke who is an actor, as well, though these two are definitely the most recognizable. Well, except from one another.
Mary-Kate and Ashley Olsen
Mary-Kate and Ashley Olsen became famous on the show Full House. And, of course, they had to look alike — these fraternal twins were playing the same character! While they started off playing Michelle Tanner, they went on to star in tons of movies as child actresses. Now they mostly stick to their fashion careers, but their other sister, Elizabeth, whom most of us hadn't heard of until recent years, has become the actress of the family.
Tia and Tamera Mowry
Tia and Tamera first gained recognition when they starred in the quirky and hilarious show, Sister, Sister. The identical twin sisters then starred together in the Disney Channel Original Movie Twitches and its sequel, Twitches Too, before embarking on solo projects. The duo have remained very close and are still in the public eye. They've done reality TV, hosted talk shows, and more. Of course, we still can't tell them apart.
Cameron and Chimene Diaz
While many celebrity siblings end up becoming known, not all celebrity siblings like the public eye. Cameron Diaz's sister, Chimene, is someone whom we haven't seen much of over the years, though she has stepped out in front of cameras with Cameron a few times. When she did, all anyone could talk about was how much the two looked alike.
Jessica and Ashlee Simpson
Jessica and Ashlee Simpson have always had very different styles. Still, it's undeniable that the two are related! They look so much alike and are probably one of the most famous sets of sisters in the world. They've both had singing careers, as well as fashion careers, and the sisters remain very close.
Fed and Ben Savage
Both Ben and Fred Savage began their careers as young actors — Fred on The Wonder Years and Ben on Boy Meets World. They also both took breaks from show business to attend college. We will always recognize their faces because of their early accomplishments, but we still have a hard time telling them apart.
James and Dave Franco
No one knew James Franco had a brother until fairly recently. But with the release of The Disaster Artist in 2017, everyone was suddenly talking about not just one Franco, but two. These brothers look so much alike and are great friends, as well as coworkers, and they've definitely made their mark on Hollywood.
Ralph and Joseph Fiennes
Ralph and Joseph Fiennes are two of the most respected actors on the planet. They've both starred in some incredible projects over the years. Ralph is the eldest of six children, including Joseph. While Ralph has played many iconic roles, he is best known among the younger generation as Lord Voldemort from the Harry Potter films. While Joseph recently appeared in The Handmaid's Tale, he is probably most famous for his starring role in Shakespeare in Love.
