@jes_chastain Yo The Martian is so good wtf 👽💋 how can the rest of us make movies now and don't feel like shit.— Xavier Dolan (@XDolan) October 11, 2015
It all began with a tweet from the director Xavier Dolan (It's Only the End of the World, Mommy) to the actress Jessica Chastain (The Zookeeper's Wife, Miss Sloane) back in 2015.
@jes_chastain I thought you hated me. I can't wait either. Next spring. Now introduce me to Sebastian Stan, my future husband.— Xavier Dolan (@XDolan) October 23, 2015
@XDolan so live in outerspace with you and Seb...? Ok, yep, Im there.— Jessica Chastain (@jes_chastain) October 23, 2015
Someone with a lot of time on their hands photoshopped a picture of Sebastian Stan and Dolan together and tweeted it at him, which he retweeted to Chastain.
Then a year and half later, Chastain posts the picture on her Instagram to wish Dolan a happy birthday.
Sebastian Stan must have finally been made aware of Dolan's stanning, because he commented on Jessica's Instagram post.
Dolan then shamelessly flirts with Sebastian in reply.
