Celebrities such as Taylor Swift, Emma Watson, and Cardi B are already household names. But what about their siblings? We might see them joining their famous other halves on red carpets or making appearances in their Instagrams, but, for the most part, celebrity siblings like Austin Swift, Alex Watson, and Hennessy Carolina are nobodies to the majority of the public. However, that might not be for long.

Lottie Tomlinson, Sister of Louis

You probably know Lottie Tomlinson’s older brother, Louis Tomlinson, a.k.a. one-fifth of the world-famous boy band One Direction. But did you know that Louis's little sister was a respected makeup artist on her own?  Lottie, whose full name is Charlotte, began as a professional makeup artist and stylist on One Direction's 2015 tour. After that, she became the ambassador of Nails Inc, one of the top-selling nail polish brands in the United Kingdom. In 2017, Lottie released her first book, Rainbow Roots: #MAKEUPBYME, which contained more than 40 makeup tutorials. (Did we mention that she was hired as a makeup artist on Selena Gomez's tour?) This success, along with the 3 million people who follow Lottie for her makeup tips and tutorials, is a good sign for her future.

Hennessy Carolina, Sister of Cardi B

Before Cardi B was a chart-topping rapper, she was an Instagram influencer who shilled fashion lines and beauty products. Now, her younger sister, Hennessy Carolina, might be following in her footsteps. Hennessy—who, like her older sister, was named after an alcohol brand and appeared on VH1's "Love and Hip-Hop"—already boasts more than 2 million followers on Instagram. So far, she's hawked big-name brands like Fashion Nova and Flat Tummy Tea (favorites of the Kardashian-Jenners), making more than $50,000 a month, according to Cardi. With sponsored club appearances and a fashion line waiting in the wings, Hennessy is only a few steps away from becoming a well-known influencer, à la the Kardashians or Blac Chyna

Cameron Robbie, Brother of Margot

Margot Robbie might be an Oscar-nominated actress, but it's her younger brother, Cameron Robbie, who is catching the internet's eye. Margot's younger brother became an internet sensation during this year's awards season for his thirst-trap Instagrams and dashing good looks. So far, the 23-year-old is poised to have a career like his sister's. He already has an impressive acting résumé, with roles in 2015's "Gifted" and 2016's "People You May Know," and he's trying to break into modeling as well. With a role in his A-list sister's production company, LuckyChap Entertainment, Cameron, who boasts more than 50,000 Instagram followers, will likely be on the big screen and runways very soon.

Beanie Feldstein, Sister of Jonah Hill

If you've watched 2017's "Lady Bird," you likely know who Beanie Feldstein is—or you've at least fallen in love with her performance as Lady Bird's charismatic best friend, Julie. But did you know Beanie is actually the younger sister of Jonah Hill? (Jonah uses his middle name as his last name, which is why he doesn't go by Feldstein.) Along with an award-nominated performance in "Lady Bird," Beanie's résumé proves she's an actress to watch.

Beanie, who's best friends with Tony winner Ben Platt, has appeared in big-name shows such as "Orange Is the New Black" and "Will & Grace" and acted alongside the likes of Zac Efron and Chloë Grace Moretz in "Neighbors 2." Currently, she's appearing on Broadway in "Hello, Dolly," opposite Bette Midler, proving that she's a threat onscreen and off. 

Austin Swift, Brother of Taylor

If you're a Taylor Swift fan, you likely know who Austin Swift is. He's the guy sometimes lurking around her concerts or sitting beside her at awards shows. But Austin, who was profiled by Vanity Fair in 2017, aims to be a serious actor. He has worked with big-name stars such as Ben Affleck in 2016's "Live by Night" and Pierce Brosnan in "I.T." and starred in 2018's "Cover Versions" with Drake Bell and Katie Cassidy. He's not a household name yet, but with roles like these, Taylor soon won't be the only famous Swift in the family.

India Yelich-O'Connor, Sister of Lorde

Though music runs in India Yelich-O'Connor’s blood (there are more than 800,000 listens on her SoundCloud cover of A Great Big World's "Say Something"), it's writing that she wants to get into. India, the younger sister of Lorde, released her first book of poetry, Sticky Notes, in February, and boasts close to 30,000 followers on Instagram, where she also shares her poetry. Though India has dabbled in acting, writing seems to be where she wants to stay.

Lottie Moss, Sister of Kate

Lottie Moss might be two decades younger than Kate Moss, but her career is already starting to resemble her big sister's. Lottie, who is also represented by the agency that discovered Kate, Storm Management, has modeled for Calvin Klein and walked in Paris Fashion Week for reputable designers including Sonia Rykiel. Though Lottie is on the short side for models (she's only 5'5), she's already making an impact, with a recent body-positive collection for PacSun.

Alex Watson
Alex Watson, Brother of Emma

With big-name movies such as "Harry Potter" and "Beauty and the Beast" under her belt, Emma Watson is one of the most well-known actors in the world. Now, her brother, Alex Watson, might join her. Though Alex hasn't made a name in acting yet, he's established his footing in the fashion world with a 2010 campaign with Burberry—alongside his big sis, of course. He's also starred in a music video for British superstar Pixie Lott and has walked in London Fashion Week. Currently, he's signed with Storm Management, the same agency that represents Kate Moss.

Stella Hudgens, Sister of Vanessa

Vanessa Hudgens’s look-alike little sister, Stella Hudgens, might be known for more than her resemblance very soon. Stella, who boasts more than a million Instagram followers and has partnered with brands such as Miss Guided, is an up-and-coming actor who has starred in shows including NBC's "Powerless" (alongside her big sister) and "According to Jim," opposite Jim Belushi. Stella, who is also close friends with big names such as Willow Smith and Bella Thorne, has also dabbled in modeling, including a 2015 campaign with Mudd, alongside Noah Cyrus (a.k.a. Miley's little sister) and Cody Simpson.

Mackenzie Ziegler, Sister of Maddie

Like her older sister Maddie Ziegler, Mackenzie Ziegler is growing up in the spotlight. She started on Lifetime's "Dance Moms" when she was 7 years old and transitioned into a Gen Z–favorite actor and singer. Though she hasn't reached the superstar-level fame that Maddie has (largely due to Maddie's muse status with Sia), Mackenzie's career isn't something to ignore. In addition to acting on Nickelodeon's "Nicky, Ricky, Dicky & Dawn," Mackenzie has also released several hit songs, including her 2016 debut "Day & Night" and 2017's "Monsters (AKA Haters)," which have both racked up more than 13 million views on YouTube.
