Robbie was spotted by Twitter users at an airport reading an unidentified comic, until one eagle eyed Reddit user (via CinemaBlend) noted that Robbie is reading Harley Quinn Valentine’s Day Special.
One of the best things to come out of an up and down 2016 for the DC Extended Universe was the first appearance of Margot Robbie as Harley Quinn.
Ultimately, she has been granted her wish in the form of Gotham City Sirens, a project that will re-team her with director David Ayer.
Robbie herself has taken a major interest in the character and was the one to pitch the idea of a Harley-led film to WB.
