Last week, we (and the rest of the Internet) had our minds blown when we learned about Rosie Mac, the 18-year-old model who acts as a Daenerys stunt double on Game of Thrones—mainly because when in costume, Mac and Emilia Clarke are pretty much impossible to tell apart.

Ever curious about what professionally playing someone's doppelganger entails, we reached out to the English-born, Spanish-raised Mac for an inside look at her current gig. And while she couldn't really give us any deets on the ins and outs of her job (they keep Westeros on lock!), she did give us a little peek into how she scored the part, as well as what Clarke has to say about seeing her identical twin walking around set all day.

Tell us about your background and how you landed the part.
I have modelled from the age of 14, but have been involved in the [entertainment] industry since I was seven. They were casting in Spain for Game of Thrones in general (extras, etc.), but I didn't get to go to the casting because I was so busy. By coincidence I had uploaded an image of me with a similar hairstyle to Khaleesi, and an agent picked it up and sent it in. I got an amazing call saying that I had been chosen as the double of Daenerys. I thought it was a prank call!

Were you a fan of the show beforehand?
Yes, a very big fan! I had Daenerys on my wall and as the background on my phone.

What does a typical day on set look like?
I really can't get into the details, but I will say that you have to be an early riser: 3 or 4 a.m.!

Wow! Do you have to sit a long time for hair and makeup?
Actually, no makeup at all—I have a scrubbed face. But the hair takes many hours.

Do you hang out with the cast or other doubles on set?
Yes! Everyone was one big team. And when me and the other doubles had spare time on set, we would have rapping and beatboxing contests—so that was quite a fun way to amuse ourselves during the long hours of filming.

Is it weird walking around set with Emilia when you two look so much alike?
We had little side jokes—like, "Hey, I'm seeing double." She's a very friendly, lovely girl. But overall, everyone is very, very busy.

Do you see yourself doing this for awhile or do you have other stuff in the works?
I do many things! I have many offers at the moment, and I also released my first single, "Done and Finished," which will be out on iTunes in May.
