Lady Gaga appeared on Jimmy Kimmel Live! on October 1st to promote her upcoming film ''Joker: Folie à Deux'' and its companion album ''Harlequin.'' 

It’s a big month for Gaga fans: She stars alongside Joaquin Phoenix as Lee Quinzel in Joker: Folie à Deux, out on October 4, and just this past weekend she released Harlequin—the film's accompanying album. The superstar hit the London premiere of Joker last week and hosted a private listening party of the album for fans. Between the two events, Vogue caught up with the October cover star still sporting her custom Celine red carpet ensemble, as she shared her creative process for the two projects.

It has just been announced that Lady Gaga is set to perform on Jimmy Kimmel Live in Los Angeles to promote her upcoming album ‘Harlequin’ next week.

In true Lady Gaga fashion, the pop icon and Academy Award-winning actress brought her signature blend of glamour, wit, and theatrical energy to The Graham Norton Show.

Along with director Todd Phillips, they opened up about the challenges of creating the sequel. Gaga, who stars as Harley Quinn, talked about how the depth of Arthur Fleck (Phoenix) attracted her to the project.
