Jennifer Lopez attended the 2019 Costume Institute benefit gala at the Metropolitan Museum of Art with Alex Rodriguez last night. Both were dressed in Versace.

Jennifer was adorned with Harry Winston jewels, including a purple sapphire-and-diamond necklace, featuring a 65.32-carat cushion-cut purple sapphire set in a cluster of round brilliant, pear- and marquise-shaped diamonds.
