In a viral clip that has been making the rounds, Joaquin Phoenix gave Lady Gaga a nudge to join in the applause, which had everyone in stitches.

Joaquin Phoenix, Lady Gaga and director Todd Phillips recently stole the show at the Venice International Film Festival with the world premiere of Joker: Folie à Deux. This sequel to 2019's Golden Globe-winning Joker promises to be a genre-hopping extravaganza. But the cinematic spectacle did not end there.

A poignant video from the screening shows the Bad Romance singer in a mild panic, seemingly overwhelmed by Phoenix's gesture. Did he give her a piece of his mind for not standing up to soak up the applause or just nudge her to take her share of the limelight?

This moment is buzzing on social media and it's safe to say that Gaga's confused expression has been the cherry on top of this already incredible premiere.
