THREE KEY DEALS FOR LADY GAGA: Throw a dart at any big project in the entertainment industry and it's a safe bet you'll hit someone this bicoastal law firm represents. Its clientele runs the gamut -- from Spotify and Facebook to the major labels and their biggest artists -- which has helped ease negotiations among its industry clients. "They understand they need each other to move forward," says Grubman. In 2018, Meiselas worked closely with Lady Gaga -- shepherding deals for A Star Is Born, the Academy Award-nominated star's Las Vegas residency and her upcoming new album -- along with The Weeknd, Bebe Rexha and Ella Mai.
