Camila Alves took Levi and Vida for a stroll around NYC yesterday, while Matthew McConaughey's thin frame was on display as he returned to their hotel separately. Camila and the kids are spending time with Matthew on the East Cost as he films his The Wolf of Wall Street. Matthew shares the screen with Leonardo DiCaprio in the Martin Scorsese-directed film centered around the financial world in Manhattan circa 1990. Earlier this week, Matthew and Leonardo arrived on set to get down to work. Matthew and Leo will also be joined by Jonah Hill and The Artist's Jean Dujardin in the new project.
