Their closeness as sisters was well-documented on Bravo’s “The Real Housewives of Miami,” starring Joanna, who recently announced plans to divorce her nightclub mogul husband, Romain Zago.

Joanna wore a sleek black dress, and as the bride-to-be, Marta was dressed in white. The ladies started their dinner with a champagne toast, and then dined family-style on crispy rock shrimp, Alaskan king crab cake, bone-in New York strip and more.
