Popsugar Fashion Oscars Memes About Lady Gaga's Necklace at the 2019 Oscars Wait a Minute: Did Lady Gaga Steal the Isadora Diamond From How to Lose a Guy in 10 Days? 25 February 2019 by Kelsey Garcia Image Source: Getty / Frazer Harrison Lady Gaga's look at the 2019 Oscars left viewers wondering, "Wasn't she wearing the Isadora Diamond?" (Well, probably right after, "Damn, she looks incredible.") At the award show on Feb. 24, the nominated A Star Is Born actress accessorised her sleek Alexander McQueen gown with a striking 128-karat Tiffany and Co. necklace last worn by Audrey Hepburn during a promotional photo shoot for Breakfast at Tiffany's. While we accept the fact that she was channelling the iconic actress, we also can't help but feel as though Gaga was really inspired by the yellow diamond at the centre of several scenes in How to Lose a Guy in 10 Days — yes, the one Kate Hudson wore with her memorable yellow backless gown. We're not the only ones either: Twitter was, of course, quick to point out the resemblance as well. Look ahead for all the proof you need.
