We know what Lady Gaga’s doing in the upcoming sequel to The Joker movie, with director Todd Phillips giving us our first look at the singer/actress in action alongside Joaquin Phoenix. Lady Gaga is presumed to be portraying Harley Quinn in #Joker2, but in the image shown it appears this might be a bit early on in the film, with her serving the role of Dr. Harleen Quinzel. #TheJoker2 will be part of James Gunn and Peter Safran’s DC Elseworlds movie slate.
