Washington [US], August 5 (ANI): American singer-songwriter and actor Lady Gaga has confirmed her casting in 'Joker 2' by posting a musical teaser on her social media.

In June, it was reported by Variety, that Gaga was circling the role of Harley Quinn in the upcoming 'Joker' sequel, which is set to be a musical.

On June 7, director Todd Phillips posted the screenplay's cover on Instagram and revealed that the 'Folie a Deux' subtitle.

The phrase refers to a shared delusional disorder, and Joker's only real companion, other than Batman, anyway, has been Harley, a character first created for 'Batman: The Animated Series' in the early 1990s. However, the teaser does not outright confirm Gaga is playing Harley.
