Jessica Biel and Marion Cotillard Do the Front Row in Dior

Jessica Biel, who wore a glamorous Dior gown, joined the face of the brand, Marion Cotillard, for Dior's Cruise Collection show on Saturday in Monaco. Also in attendance for the fashionable affair were Liv Tyler and Ruth Wilson. Marion switched her focus from jewels to dresses for the runway show after she attended a Chopard lunch at the Cannes Film Festival on Friday. The event took an unexpected turn after $1 million worth of Chopard jewelry was stolen the night before the celebratory occasion.

Jessica popped up in Monaco while her husband, Justin Timberlake, took care of business not far away at the Cannes Film Festival. Justin attended a photocall with his costars Carey Mulligan, Garrett Hedlund, and Oscar Isaac for their new Coen brothers film, Inside Llewyn Davis today.
