Jennifer Lawrence dressed up in a Dior gown to hit the red carpet at the Cannes Film Festival for the Jimmy P.: Psychotherapy of a Plains Indian premiere tonight. She was joined by her Catching Fire crew: Liam Hemsworth, Sam Claflin, and director Francis Lawrence. Also in attendance to show their support for Jimmy P., which stars Benicio del Toro, were Calvin Klein-clad Doutzen Kroes; Eva Longoria, who wore Atelier Versace; and Jane Fonda. Steven Spielberg, who is serving as one of the jurors at this year's festival, was joined by wife Kate Capshaw for the glamorous event at the Palais des Festivals.

It was quite the day for Jennifer and her men, who were busy promoting their own film in Cannes this morning. Jennifer, Liam, and Sam posed for a Catching Fire photocall after Liam hit the town last night for the Belvedere bash.

Jennifer Lawrence and Liam Hemsworth linked up with their Catching Fire costar Sam Claflin this morning for a photocall at the extremely rainy Cannes Film Festival! The trio were able to escape the elements by posing inside the Majestic hotel. Jennifer, Sam, and Liam are in France to hype up the second installment of The Hunger Games series, which is out in the US on Nov. 22. Also smiling for the cameras were Lionsgate cochairmen Rob Friedman and Patrick Wachsberger and director Francis Lawrence.

The cast and team behind the film are busy despite the release being six months away. It was just announced that CoverGirl will launch the Capitol Collection, a range of makeup products inspired by the film. And Liam made sure to enjoy the social side of Cannes, too. Last night, he and a group of guy friends checked out the Rev Run and DJ Ruckus set at Belvedere's party inside the VIP Room club.

Liam Hemsworth stepped out with a group of guy friends last night in Cannes at Belvedere's big soiree. The actor was one of several celebrities in attendance: Solange Knowles also arrived just before Rev Run and DJ Ruckus took to the turntables to spin a set full of throwback hip-hop for the crowd. The Help's Ahna O'Reilly also made an appearance at the party, which was nestled in an underground VIP space in the JW Marriott, right in the heart of the city's bustling festival scene.

Liam is in Cannes to celebrate the Hunger Games franchise, while Miley Cyrus has been tweeting about spending time in the recording studio back in the states as she works on new music. Liam's second film in the series isn't screening during the festival, but the cast — including Jennifer Lawrence — gathered today for a Catching Fire photocall, and Lionsgate is throwing a bash in honor of the film later tonight.

Zooey Deschanel is the queen of quirky nail art designs. With New Girl as funny as ever, Zooey always finds a way to makeup us laugh with her slapstick comedy. Hopefully this roundup of her best manicures will keep you smiling and inspire an impromptu trip to the salon — even some DIY nail sessions at home.

Today, Calvin Klein officially unveiled Rooney Mara as the face of its newest fragrance, Downtown — but the brand got an early start celebrating the news last night. Despite the rain, stars including Rooney, Carey Mulligan, Nicole Kidman, and Skyfall's Naomie Harris stopped by Calvin Klein's beachside bash at the Cannes Film Festival yesterday evening.

Rooney marked the new partnership alongside Francisco Costa, the creative director of Calvin Klein Collection, at the party, which was also hosted by Belvedere and IWC. Inside the dimly lit and intimate soiree, she chatted with producer Harvey Weinstein, while Carey mingled by the DJ booth before making an early departure. Nicole also made time in her Cannes schedule to attend. All three actresses are busy working this week. Carey's The Great Gatsby premiered on opening night; Rooney's latest film, Ain't Them Bodies Saints, will also debut later this week; and Nicole is serving as a member of the film festival's official jury.

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.
