12 Celebs You Didn't Know Were Twins (No Mary-Kate & Ashley Here!)

When I was growing up, I was always a fan of the Olsen twins as Michelle Tanner on Full House, and Sister, Sister was one of my after school staples, because I was always thinking it would be the coolest thing on Earth to have an identical twin sister. I have a younger brother, but we look absolutely nothing alike, so I was fascinated by the idea of twins. While there are a few well-known and famous celebrity twins out there (like the Olsens and the Mowrys), there are quite a few celebs who you probably didn't know have twins.

Being that they're probably going to be fairly similar (you know, having, in some cases, identical genes and all), it's interesting to see which of these twins also work in the entertainment business and which ones decided to take an entirely different route in their lives. I mean, it would be totally weird to have two actors who look exactly alike vying for the same roles, right?

It turns out, some super surprising celebrities have identical twins who also act, and you've probably watched both of them, which will send your brain into a big black hole of confusion. Without further ado, here are 12 celebrities you might be surprised to find out have twin siblings.

1. Rami Malek

Mr. Robot star Rami Malek has an identical twin brother, Sami, who is four minutes younger than him. Malek spoke about his brother on Jimmy Kimmel Live and fans caught a glimpse of Sami, who is quite the babe himself.

2. Gisele Bündchen

Could you imagine your sister being one of the most recognizable and highest paid supermodels ever? Bündchen's fraternal sister, Patricia, is not a model but she is just as gorgeous as her sibling.

3. Alanis Morissette

Alanis Morissette's twin brother, Wade, is also a musician, but has focused his life on being a yoga instructor and therapist.

4. Jon Heder

Jon and Dan Heder are absolutely identical and I can't even tell who is who in this photo above. Where are you Napoleon Dynamite?? Dan works behind the scenes in visual effects and has acted in very small parts, but left the acting thing to his brother.

5. Keifer Sutherland

Keifer Sutherland was born seven minutes before his younger twin sister, Rachel, who works as a post-production supervisor.

6. Scarlett Johansson

Hunter Johansson has been spotted on the red carpet supporting his sister, Scarlett, and while he has acted in a few things, he has turned his eye more toward politics. The siblings hosted a Hurricane Sandy benefit back in 2012, a cause they were passionate about as native New Yorkers.

7. Aaron & Shawn Ashmore

This was the one that blew my mind. Up until a few months ago, I had no clue that the guy in X-Men, Smallville, Veronica Mars, and more was actually two different actors! Shawn and Aaron Ashmore are identical twins who both act, so I suggest looking at their individual IMDb pages to try to make sense of it all, because I can't.

8. Samantha Ronson

You may have heard of both of these siblings, but just not realized they were twins. Samantha Ronson is the DJ famous for being Lindsay Lohan's ex-girlfriend, and her twin sister, Charlotte, is a successful fashion designer.

9. Eva Green

The Dreamers star Eva Green has a non-identical twin sister, Joy, who she has admitted she is not very close with. In an interview with Film Lounge in 2003, the actor said of her sister, "We're so different. We don’t really talk to each other. She hasn’t seen my plays, but now she wants to see my movie, and I’m very moved. She’s studying business. She’s more down-to-earth.

10. Tasha Smith

Tasha Smith is known for her roles in Meet the Browns and Why Did I Get Married Too, and she has an identical twin sister, Sidra, who also works in the business as a casting director and producer.

11. Parker Posey

Giovanni Ribisi has a twin sister, Marissa, who is notable for her role in Dazed and Confused. She is also married to musician Beck, whose mother reportedly delivered Marissa when she was born. How... romantic?

I don't think this list helped me in my twin jealousy one bit.
