Lady Gaga had all heads turning as she walked the red carpet for her film 'Joker: Folie a Deux' premiere at the Venice Film Festival. For the big night, Gaga walked in with her fiance Michael Polansky. This is the first time that the duo appeared together in public after more than four years together.

Lady Gaga knows how to make a fashion statement. She had all heads turning with her all-black ensemble. She effortlessly walked the red carpet in a voluminous gown and dramatic headpiece. The gown was by Christian Dior Haute couture. However, the true showstopper was her dramatic headpiece designed by Philip Treacy. It is a vintage headpiece and was first worn by fashion legend Isabella Blow in 2001.
