The world knows its fair share of celebrity twins. Among the most famous are the Olsen twins, and Beyoncé's twins Rumi and Sir Carter. While fans want to know everything about their favorite celebrity, they rarely extend that interest to their siblings. What they often never realize is that their favorite celebrity has a twin sibling.

It's hard to imagine that there is an identical copy of certain celebrities walking around somewhere and living a life away from the spotlight. Most A-listers have a non-identical twin though, and sometimes, they barely resemble one another.

10 Eva Green

Eva Green is most famous as the Bond girl from Casino Royale (2006), but she has since appeared in several movies and TV shows, such as Miss Peregrine's Home for Peculiar Children (2016) and Penny Dreadful.

The 40 year-old French actress has a non-identical twin sister, named Joy Green. According to Hello Magazine, she lives in Italy and runs a wine company together with her husband. Eva even joked that she is the other, happier version of herself.

9 Kiefer Sutherland

Both Kiefer and his twin sister Rachel work in the entertainment industry. She works as a post-production film supervisor. Among her most recent projects are Nurses (2020) and Mary Kills People (2017).

The Sutherland twins were born in London, but they later moved to Canada as both of their parents are actually Canadian. They both have a dual citizenship.

8 Ashton Kutcher

Born in the Midwest, Ashton Kutcher started out as a model and only later moved to Hollywood and built his acting career. His twin brother Michael is mostly known for being related to Ashton, but he is also a businessman and a public speaker.

He advocates for people with cerebral palsy, the permanent movement disorder he was diagnosed with at the age of three. When he was thirteen years old, he almost died from cardiac arrest. He was lucky, though: he had a successful heart transplant.

7 Scarlett Johansson

Scarlett Johansson has a twin brother, named Hunter. When she's wearing makeup, the resemblance is not as obvious as on the pictures where she went makeup-free.

Hunter has a heart of gold. He founded Solar Responders, a charity that responds to natural disasters. When Hurricane Maria devastated Puerto Rico, the organization provided solar panels to help the country get back on its feet.

6 Rami Malek

The Bohemian Rhapsody star has an identical twin brother whose name rhymes with his: they are Rami and Sami Malek. They also have an older sister Yasmine and she is a doctor.

5 Giovanni Ribisi

Giovanni and Marissa Ribisi are both well-known in their circles, but Giovanni is still the one twin that will more likely ring a bell. On television, he portrayed Frank Buffay, Jr.  in Friends, and Jeff Billings in The Wonder Years. His filmography is also impressive; he appeared in Avatar (2009), Ted (2012), and Selma (2014).
