Castmates Brendan Gleeson and Lady Gaga shared a brief hug and kiss on the Oscars carpet while filming for their highly anticipated Joker sequel continues.

Gaga is set to star as queen of chaos Harley Quinn in Todd Phillips’ Joker: Folie à Deux, which will see the return of Joaquin Phoenix’s Arthur Fleck in the title role.

Far away from the streets of Gotham City, the pop star, 36, and Gleeson, 67, were pictured embracing on the champagne-coloured carpet.

Gleeson was nominated for best supporting actor for his performance in The Banshees of Inisherin, which he lost on the night to Ke Huy Quan for Everything Everywhere All At Once.

His role in the anticipated sequel, which saw Phoenix nab the Academy Award for best actor in 2020, is not yet known as the project remains shrouded in mystery.

Meanwhile, Rihanna and Lady Gaga will go head to head at the Oscars for best original song.

The nominees for the category were Lift Me Up from Black Panther: Wakanda Forever sung by Rihanna; Hold My Hand by Lady Gaga from Top Gun: Maverick; Applause by Diane Warren from Tell It Like A Woman; Naatu Naatu by MM Keeravani & Chandrabose from RRR; and This Is A Life from Everything Everywhere All At Once.
