Marion Cotillard

Marion Cotillard got dressed up in a Dior gown to join her costars Zoe Saldana, in Valentino, and Clive Owen and director Guillaume Canet on the Cannes red carpet for the premiere of their film Blood Ties this evening. It was a busy day for the crew since they got together for a photocall and press conference at the film festival this morning. Marion and her partner, Guillaume, who directed her in Blood Ties, were able to sneak in a kiss while celebrating the film together earlier today. Missing from the action was Mila Kunis, who is also in the film but currently stationed in London shooting Jupiter Ascending.

Marion has been making the rounds in France since last week, stepping out for the Chopard lunch on Friday and making a fashionable stop in Monaco to fulfill her duties as the face of Dior at the brand's cruise collection runway show on Saturday.

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.

Marion Cotillard donned a strapless Vivienne Westwood gown to join Colin Firth at the Chopard lunch as part of the festivities for the Cannes Film Festival today. Marion and Colin celebrated the jewelry brand, which is responsible for creating the festival's Palme d'Or trophy, as well as best actor and actress awards. The celebratory lunch comes at an interesting time for the brand since it was revealed that $1 million worth of Chopard jewels were stolen from a hotel room in Cannes last night. The jewelry was to be loaned as red carpet pieces to the stars at the festival. Many drew comparisons between last night's burglary and the film, The Bling Ring, which coincidentally debuted at the festival yesterday, since the movie is based on the real-life case of teenage burglars who robbed the Hollywood homes of celebrities.

Nicole Kidman, Carey Mulligan, and Julianne Moore are the latest in a long list of fashion darlings and actresses to take Raf Simons from the runway to the red carpet. Ever since Belgian designer Simons, formerly of Jil Sander, took the reins at the legendary label, he's presented five exquisite collections. Naturally, stars like Cotillard (the face of Lady Dior) and Jennifer Lawrence (the face of Miss Dior handbags) have flocked to his jaw-dropping gowns, and we can totally see why. Simons is breathing new life into the design house by taking iconic past-collection references (think New Look from the 1940s) and updating them with a modern twist. Step inside to see all the stars who have donned Simons's designs for Dior now.

Our position on the red carpet at last night's Met Gala afforded the chance to observe what really takes place on the storied red carpet! It was model, designer, and actor madness as guests headed in to celebrate the opening of the Metropolitan Museum of Art's Costume Institute exhibit Punk: Chaos to Couture.

Veteran attendees Gisele Bündchen and her husband, Tom Brady, shared a run-in with first-timer Kim Kardashian on the carpet, while a Valentino-clad Gwyneth Paltrow caught up with her good friend Jessica Seinfeld. Kristen Stewart wasn't bothered by the stars like Sarah Jessica Parker and Jessica Biel mingling outside the Metropolitan Museum of Art, though her pal Jennifer Lawrence did do a bit of socializing with her fellow Dior spokesperson Marion Cotillard.

Marion Cotillard planted a sweet kiss on her son Marcel's cheek while cheering on Guillaume Canet at the International Jump Bost in Barbizon, France, on Sunday. Marion and Marcel cuddled to keep warm during the sweet outing, where they watched Guillaume show off his skills on his horse. She returned to her native France for the family fun following a recent trip to Tokyo, where she donned a Christian Dior gown for an event to promote her film Rust and Bone at the end of last month. Earlier, Marion showed support for her husband when she attended Guillaume's Paris premiere of his film Jappeloup back in February.
