Kristen Stewart and her Snow White and the Huntsman costar Sam Claflin popped up in Mexico City this afternoon. The duo did press at the St. Regis Hotel after promoting the film in Europe last week. Kristen and Sam made appearances in London, Berlin, and Madrid where they were also joined by Charlize Theron. Leading man Chris Hemsworth attended the exciting UK premiere but didn't continue on the rest of the itinerary with the cast since he welcomed his first child just over a week ago. Chris debuted baby India Rose during a walk in London with his wife, Elsa Pataky.

The guys and girls of Lawless hit the red carpet for a premiere of their movie at the Cannes Film Festival this evening. Shia LaBeouf, Tom Hardy, and Guy Pearce appeared on the Croisette in tuxes, while their leading ladies Jessica Chastian and Mia Wasikowska donned gowns. Special guests like Sean Combs and Bérénice Bejo walked the press line as well. Shia, Tom, Jessica, and Mia have had a busy day, chatting up the press and posing for pictures at an a.m. photocall. The film, based on the book The Wettest County in the World, is out in the US on Aug. 31, and the Lawless reviews are so far good.

Shia spoke about Lawless and how it's a good representation of the movies he'd like to be making. He said, " I'm going to be doing things that I like for a while, until the business says, 'No, we need you to do this, or you can't work.'" Jessica has been especially busy around the festival since she has another film screening. Madagascar 3: Europe's Most Wanted premiered yesterday, and Jessica wore Armani Privé for that event alongside costars in the animated picture like Jada Pinkett Smith and Chris Rock.

Eva Longoria was on a boat last night to party the evening away at Cannes. Her boyfriend of over a year, Eduardo Cruz, jetted to France to get in on the film festival fun. Eva's been making the rounds in the south of France as one of L'Oréal's brand ambassadors. Yesterday was a busy one for Eva, since she recorded an interview for France's Le Grand Journal and a pretaped spot for Today. For the latter chat, Eva donned a dress designed by her "dear friend" Victoria Beckham. Eduardo's been in town with her since the start of the festival. On Wednesday night, he tweeted a picture of fireworks with the caption "love it!"

Pippa Middleton dressed up to watch friends Camilla Hook and Sam Holland get married at Aberlady Parish Church in East Lothian, Scotland, today. She wore a red dress and netted fascinator and was joined by a female pal for the occasion. Pippa's been lying low since last month's controversial appearance in Paris where a guy friend pulled a fake gun on photographers during a drive. She's reportedly moved on from the incident with recent rumors that she's setting her sights on a move to NYC. Pippa also has her party-planning book, Celebrate, coming out in October. Meanwhile, sister Kate has been busy with royal engagements, including a reception with Princes William and Harry just yesterday.

The Cannes VIP Room was the place to be on Friday night as Belvedere and RED threw a party with a performance from Cindi Lauper. Rolling Stone Ron Wood joined her onstage to entertain the crowd. Bridesmaids leading man Chris O'Dowd hit the red carpet and a banquette with his fiancée Dawn Porter. He's in the South of France chatting up his new movie The Sapphires.

They're among the many celebrities at Cannes this week — make sure to check in on PopSugar's Twitter for updates from the scene!

Shia LaBeouf and Tom Hardy play brothers on the big screen in Lawless, which they debuted at the Cannes Film Festival in Cannes, France, today. The two made a handsome pair at their morning photocall, where they joined their leading ladies Jessica Chastain and Mia Wasikowska. Shia was sporting a well-manicured scruff while Tom has clearly been growing out his facial hair. Jessica has been the belle of the ball at the festival so far, hitting up many red carpets and also promoting Madagascar 3: Europe's Most Wanted yesterday. The film, which was formerly called The Wettest County in the World, has its big red-carpet premiere later on Saturday. The movie was met by positive reviews from the press who checked out the first screening. We had a chance to see Lawless this morning and will be chatting with the cast tomorrow.

David Beckham had the honor of bringing the Olympic Flame from Athens, Greece, to England yesterday. He participated in a welcome ceremony in his home country that marks the beginning of a 70-day relay for the flame before the start of the 2012 Summer Olympics in London. The flame has since moved into the hands of three-time Olympic sailing champion Ben Ainslie, who is the first of 8,000 torchbearers to handle the flame before it reaches London for the opening ceremonies. David spent a few days in Greece ahead of his flame duties and met up with a group of children at an Athens school.
