'Joker 2' still shows Lady Gaga's first appearance as Harley Quinn.

Earlier, "Joker: Folie a Deux" director Todd Phillips released a brand-new still photo from the set. The director unveiled Lady Gaga's first look as Harley Quinn on Valentine's Day, alongside Joaquin Phoenix.

Todd posted the image to Instagram with the caption: "Greetings on Valentine's Day. There is an air of love."

When they saw the post, fans couldn't help but comment on it in a flurry of excitement.

"One user wrote, "We're all hyperventilating!" while another wrote, "Where have I put my inhaler? I'm about to lose it."

The same picture was posted by Lady Gaga on her social media accounts. In "Birds of Prey" and "The Suicide Squad," two live-action movies, Margot Robbie played Harley Quinn.

While other details about the film remain tightly sealed, we do know that it will be a musical and an official sequel to the 2019 hit, "Joker", which earned Phoenix the Best Actor Oscar.
