Gaga, 38, showed off her huge diamond engagement ring at the premiere of her latest film, “Joker: Folie à Deux.”

Gaga, whose full name is Stefani Joanne Angelina Germanotta, walked the red carpet at the Lido di Venezia in a black Christian Dior haute couture dress with a plunging halter neckline.

Her sleeveless dress was nipped in at the waist and fell into a puffy black skirt. She wore an elaborate Phillip Treacy headpiece over her platinum blonde hair, which she tied back in a chic, sleek bun.
