Fashion Week can be a great place for artists we don't normally expect to see together to have some fun photo ops (just ask Robyn and Diddy). Alicia Keys temporarily traded her Empire State of Mind for City of Lights chic, carrying the black-and-white trend from the Givenchy event over to today's Stella McCartney show, where she also hob-knobbed with Stella's dad Sir Paul McCartney. Which of Alicia's fashion week looks did you prefer?
