Witherspoon and the Modern Family star are currently on the set of Don't Mess With Texas in New Orleans. 'Gramming up a storm between takes, the new costars have become fast friends. So far, they've snapped pics of Vergara doing Witherspoon's makeup and cute shots of the pair goofing off in costume. Variety reports their film is a "female-centered buddy comedy that will follow a police officer [Witherspoon] and a prisoner [Vergara] who are on the run." The movie doesn't come out until next year. In the meantime, though, we'll keep refreshing our Instagram feeds to see more adorable pics of the duo.
