Jessica Alba struck a pose at the Lanvin ready-to-wear Fall 2012 show during Paris Fashion Week on Friday. She was sitting next to her sister-in-law Nikki, who she brought along to partake in the fashionable festivities. Jessica arrived in France on Thursday, but her visit was a short one since she was already saying au revoir to the city of love today. Jessica chronicled her whole trip on Twitter and Instagram, sharing everything she saw and all the delicious things she ate while abroad. Jessica made a similarly quick visit to NYC for the Michael Kors runway show last month, but she doesn't seem to want to stay away from her daughters Haven and Honor and husband Cash Warren long.
