She debuted a dramatic sculptural black gown by Dior, complemented by an extravagant headpiece from Philip Treacy and stunning Tiffany & Co. jewelry, including over 22 carats of diamonds. Accompanied by her fiancé Michael Polansky, Gaga’s red carpet look was a hallmark of her theatrical style, setting the stage for an exciting promotional period leading up to the film's release on October 4. Earlier in the day, she wore a chic black dress while arriving at the venue, highlighting her versatility and glamour. The film is highly anticipated, being the sequel to the successful 2019 Joker, which garnered significant acclaim and box office success.
