Jesse Eisenberg and Mia Wasikowska were actually spotted kissing in Toronto, sparking rumors that they are dating. The duo reportedly met while filming 'The Double', which is a comedy about a man who spots his doppelganger and goes insane.

Jesse Eisenberg was reportedly dating Anna Strout for a long time
Jesse has previously raved about Mia's acting abilities while working on the Double, and he reportedly said, "She is obviously, you know, wonderful. The tone of the movie we're doing is so strange. Within any given moment we are on all ends of the emotional spectrum. All the characters in this movie navigate this very strange world of being funny, but real and tragic and whimsical, and her character is kind of enigmatic, traffic, but oddly pleasant. She is able to kind of find all these different aspects in a way that is totally consistent with the very odd tone."
It's certainly an unusual couple, but since Jesse and Mia are both incredibly private, I think we can all assume that the paparazzi weren't called there by either of them or their publicists.

Mia Wasikowska and Jesse Eisenberg are now dating
What do you guys think about Mia and Jesse dating? Jesse most recently starred in 'Now You See Me' and Mia recently starred in 'Stoker'. 'The Double' will be out later this year, and after all these reports, Jesse and Mia will likely stay off the radar for a while.
