The pair, who recorded "They Don't Know About Us" together on Duffield's Shut Up and Dance album, went Gangnam Style.
Simpson, Duffield and her crew made a parody video of Psy's horse-dance viral sensation while they were in the west coast city and it's pretty entertaining.
During the video Simpson and Duffield execute the signature Gangnam Style dance on a balcony, near a swimming pool, in an elevator, in front of an artificial waterfall, over dinner, while crossing a street, in an underground parking garage...
You should probably just watch it.
