The Brazilian model, 30, wore a simple, slim fitting green dress that hugged her figure and showed off her generous curves.
Alves and McConaughey wed last December after dating for five years. They have three children - Levi, 5, Vida, 3, and Livingston, 10 months.
McConaughey stars in the upcoming film "Dallas Buyers Club." He famously dropped a ton of weight for the movie. He lost 40 pounds to play real-life AIDS victim Ron Woodroof, who smuggled drugs into the United States from Mexico to help himself and other AIDS patients when he was given just six months to live. The film hits theaters on Nov. 1.
