And it seems she will be arriving at the premiere this summer with an interesting guest.

The blonde stunner recently realized she has a doppelganger – and even invited her to party with her at the Rough Night premiere.

She posted a video directed to a 72-year-old grandmother called Geraldine, after a Reddit user named denverjoel shared a photo of his relative who bears a striking resemblance to the Ghost in the Shell star.

The picture was taken when Geraldine was 22-years-old, and Johansson said she had been swamped by messages from people telling her about the spooky resemblance.

‘This video is for grandma Geraldine,’ Johansson said in the newly-released video message.

‘Geraldine, I cannot tell you, I have been absolutely inundated with emails and messages about how much we look alike. And I had to look at the photo myself. Holy crap.’
