The Joker 2 is one of the most exciting forthcoming comic book projects.

Joker: Folie à Deux is the name of the follow-up film directed by Todd Phillips, who also shared a picture of Joaquin Phoenix as the Clown Prince of Crime reading the script last week.

We now know who might be joining The Joker in this future sequel, riding the high of that thrilling news.

According to The Hollywood Reporter, Lady Gaga is in preliminary discussions to appear in Joker 2.

While Warner Brothers is keeping the persona Gaga would portray a secret, THR reports that it would actually be a version of the fan-favorite character Harley Quinn.

Since 2016’s Suicide Squad, when Margot Robbie introduced the DCEU continuity a separate reality from the Joker, the villain should be well known to the majority of DC movie fans.

Harley Quinn was made by Bruce Timm and Paul Dini for the popular 90s animated series Batman: The Animated series, for anyone who needs a refresher.

Over the past 30 years, Harley and the Joker’s severely toxic relationship has offered comic book readers some of the best stories in the genre.

THR did not, however, stop there; the sequel’s genre is supposedly a musical. You heard correctly.

It’s possible that Joker and Harley will sing in the rain in the follow-up to the sad criminal drama that strongly drew inspiration from movies like Taxi Driver.
