Just three days after the world got to see her buddying up to a bong, the 18-year-old starlet was "all business" upon arriving Monday to the New Orleans set of her latest movie So Undercover, a set source tells E! News.
In the film, Miley plays a private investigator hired by the FBI to infiltrate a sorority house.
Her first scenes of the day involved costar Kelly Osbourne chatting about their majors, according to the source, who added that "Miley is focused and professional."
Well, that should help, um, clear the air a bit, right?
