Celebrity siblings: They're just like us—or at least they started out that way. Yes, these famous duos (and one trio) grew up sharing bunk beds and bathrooms, and now they share the Hollywood spotlight, whether fans realize the familial connection or not. From a Cosby Show alumna and her Fame-ous sister to a British pop singer and her Game of Thrones-starring brother, here are the surprising celebrity siblings you never knew were related.

In 2006, British pop star Lily Allen released a song called "Alfie," playfully imploring her lazy younger brother to straighten out his life and get a job. And though they may not realize it, Game of Thrones fans might just have this song to thank for one of the show's most noteworthy characters: Lily's little brother, Alfie Allen, joined the hit HBO series as Theon Greyjoy in 2011. He even earned an Emmy nomination for his performance. Thanks, sis!

Shirley MacLaine (born Shirley MacLean Beaty) got her start in Alfred Hitchcock's 1955 film The Trouble With Harry. Just two years later, her brother Warren Beatty (born Henry Warren Beaty) made his debut on the small screen on Kraft Television Theater, which ultimately lead to a legendary film career.

To this day, many don't realize that MacLaine and Beatty are siblings, as both chose to alter their birth names when they got their big break. However, as MacLaine shared with Vanity Fair in 2017, the two still close. "I'm three years older, and I'm protective," said the actress.

In the mid-1980s and early '90s, Phylicia Rashad famously starred on The Cosby Show as the family's beloved matriarch, Clair Huxtable. But Rashad also has an equally talented younger sister: dancer and choreographer Debbie Allen. In fact, Allen began her legendary run on the hit series Fame in 1982, before The Cosby Show even premiered. At the time, people knew about the connection between these talented sisters. But these days, with Allen's younger fanbase courtesy of Grey's Anatomy, many millennials and Gen Zers are surprised to learn of the connection between the two.

Long before Blake Lively ever landed her starring role on The CW's teen drama Gossip Girl, her older half-sister, Robyn Lively, had a thriving acting career of her own. Back in the day, she starred in the film Teen Witch, and even had a major role on the hit show Twin Peaks. In an interview with Access Hollywood in 2017, the sisters sweetly shared that they are "best friends" and that their bond is "everything," despite their 15-year age gap.

They also have three more siblings: Robyn's sister and Blake's half-sister, Lori; Robyn's brother and Blake's half-brother, Jason; and Blake's brother and Robyn's half-brother, Eric. (Lori is the oldest and Blake is the youngest of the crew.) All five share the same mother, talent agent Elaine Lively, and all five have been in the entertainment industry. Talk about good genes!

Charlie Sheen and Emilio Estevez

Don't let their differing surnames confuse you: Charlie Sheen and Emilio Estevez are 100 percent blood-related brothers. Their father, the famous actor Martin Sheen, was born Ramón Estevez, but he chose a less "ethnic"-sounding stage name when he began his acting career. While all four of Martin and Janet Sheen's children were given the last name Estevez on their birth certificates, younger brother Charlie chose to follow in his father's footsteps and embrace the "Sheen" stage name when he got his big break. Emilio, meanwhile, stuck with his birth name in hopes of blazing his own trail in the acting world.

The sons of two entertainers, Cuba Gooding, Jr. (Jerry Maguire) and Omar Gooding (Hangin' With Mr. Cooper) were always encouraged to pursue their passion for acting. Older brother Cuba, Jr. was the first who decided to follow his Hollywood dreams, taking classes and signing with an agent in the early '80s. His younger brother Omar was later discovered by talent scouts while dropping off a script for Cuba, Jr. Omar went on to host the Nickelodeon game show Wild & Crazy Kids and to star on family sitcoms like Hangin' with Mr. Cooper and Smart Guy in the '90s.

Jesse Eisenberg is best known for his impressive performance as Mark Zuckerberg in the 2010 film The Social Network. However, long before his big break, his little sister, Hallie Eisenberg, was winning over the public in the 1998 movie Paulie and as "the Pepsi Girl." Yes, the adorable, curly-haired spokesgirl who would crack open a refreshing Pepsi in the brand's late '90s and early 2000s commercials paved the way for her big brother. She hasn't done much acting over the past decade, but it's nice of her to give the elder Eisenberg the chance to shine.

Rooney and Kate Mara

We all know Rooney Mara as the vigilante computer hacker Lisbeth Salander from the film adaptation of Stieg Larsson's novel, The Girl With the Dragon Tattoo. And Kate Mara is equally recognizable, having famously played reporter Zoe Barnes in the first season of the Netflix political thriller House of Cards. However, what many fans of these powerful actresses likely don't realize is that Rooney is Kate's younger sister. What's even more surprising than their sibling connection? These women are football royalty: Their mother's family (the Rooneys) owns the Pittsburgh Steelers and their father's family (the Maras) owns the New York Giants.

It's easy to forget that siblings Jason Bateman and his older sister Justine Bateman have been in the limelight for three decades. In the '80s, Jason started his career on Little House on the Prairie and Silver Spoons, while Justine got her big break on Family Ties. Since then, Jason has starred in hit shows like Arrested Development and Ozark, and Justine has appeared on series like Desperate Housewives and Californication. She also made a cameo on Arrested Development in 2006—and the episode was full of in-jokes if you knew about this sibling pair!

Almost Famous star Kate Hudson and Rules of Engagement star Oliver Hudson, are—unbeknownst to many—both the children of Goldie Hawn and Bill Hudson. After a messy divorce, the siblings were raised by Hawn and stepfather Kurt Russell, and were later very publicly disowned by their biological dad. The duo now works together under the banner of Kate's activewear brand Fabletics, with her big brother Oliver spearheading the men's division, FL2.

Dennis and Randy Quaid

Brothers Dennis Quaid and Randy Quaid have many things in common: parents, a love of acting, and myriad of public struggles. Younger brother Dennis's career took off in the '80s thanks to roles in Innerspace, The Big Easy, and Great Balls of Fire! But in the '90s, he struggled with drug addiction, an eating disorder, and eventually a messy divorce from America's sweetheart Meg Ryan. Older brother Randy, meanwhile, made a name for himself in the '70s and '80s—even earning an Oscar nomination for The Last Detail in 1973 and gaining a massive fanbase as Cousin Eddie in the National Lampoon's Vacation movies. But recently, he's gotten into quite a bit of trouble with the law.

Fred and Ben Savage

Fred Savage and Ben Savage both starred in a highly revered coming-of-age television series—The Wonder Years and Boy Meets World, respectively. The shows even overlapped for a bit in the early '90s—and though this could have easily been cause for jealousy or competition, the brothers shared with E! News in 2015 that they were each glad to have someone else in the house who understood what they were going through. After all, not everyone grows up in the spotlight with the whole world watching.

Jonah Hill and Beanie Feldstein

In recent years, Jonah Hill has shown the world that he is able to tackle any genre, moving on from raucous teen comedies like Superbad to more serious films like the Oscar-nominated baseball flick Moneyball. And given Hill's success as both an actor and director, it should come as no surprise that talent runs in his family. Hill's younger sister, Beanie Feldstein, earned accolades for her performance in 2019's hilarious coming-of-age dramedy Booksmart, and she also appeared in Greta Gerwig's Oscar-nominated film Ladybird in 2018.

If you weren't aware that Hill and Feldstein were related, don't feel bad: Though Hill's last name is legally Feldstein (Hill is his middle name), only his sister still uses the family name professionally. Despite the differing monikers, these two have such a special sibling bond that Hill got a "Hello, Beanie!" tattoo in 2018, in honor of his sister's performance in the 2017 Broadway revival of Hello, Dolly!

Ariel Winter is best known for playing middle sister Alex Dunphy on the popular ABC sitcom Modern Family. But in real life, Winter is the youngest of three, with an older sister and an older brother. What fans might not realize, though, is that they might already know her brother: His name is Jimmy Workman, and he famously played Pugsly in The Addams Family and Addams Family Values in the '90s. Winter's family dramas have been media fodder for years, and as People reports, she and her brother are currently estranged, ever since Workman sided with their mother when she denied Winter's abuse allegations.

Sure, their shared last name and piercing blue eyes have probably tipped a few people off, but ultimately, the majority of folks don't realize that Emily Deschanel and Zooey Deschanel are sisters. Emily is most famous for starring as the titular character on the Fox series Bones from 2005 through 2017, and Zooey is an actress, singer, and songwriter. She's best known for starring on the Fox comedy New Girl, in the 2009 movie 500 Days of Summer, and for being one half of the musical duo She & Him.

More than a decade after Nora started on SNL, her brother Kevin Dunn began his own acting career, making appearances on some of the most popular shows of the '80s and '90sCheers, 21 Jump Street, Roseanne, and Seinfeld, to name a few. These days, Kevin stars on Veep as former White House Chief of Staff Ben Cafferty. The comedy gene clearly runs in the family!
