Lady Gaga will be a sure Oscar winner tonight at the 2019 Academy Awards, and dressed to win! Up for Best Actress and Best Original Song, the songstress and actress channeled Audrey Hepburn clad in a black Alexander McQueen ensemble. The black strapless frock recalled Audrey Hepburn's Breakfast at Tiffany's style, complete with elbow length black gloves and a neat updo featuring swept swirls.

The highlight of Lady Gaga's dress was Tiffany & Co. jewels, including a 128.4 carat diamond necklace, previously worn by Audrey Hepurn for promotions of Breakfast at Tiffany's, paired with matching drop earrings. The diamonds worn by Gaga are nearly priceless, once up for bid in 1972 for $5 million, about $30 million today.

Update: Lady Gaga won her first Oscar for Best Original Song for 'Shallow' and also gave a steamy and intimate performance of the song with Bradley Cooper.
