Leonardo DiCaprio

There was a lot to keep up with in celebrity land this week! Things were kicked off by Joel Madden and Reece Mastin, who joined rock-star forces at the Madden Housewarming Party in Sydney's Point Piper on May 12. Joining her husband Joel in Sydney later in the week was Nicole Richie and their kids Harlow and Sparrow — they were spotted doing a sweet early morning coffee run at Sydney's The Star on Thursday. Over in Miami, Miranda Kerr got down to a sexy black one-piece as she worked her magic for the camera; meanwhile Carey Mulligan, Tobey Maguire and Leonardo DiCaprio stole a moment away from the crowds at Cannes as they premiered their epic new film, The Great Gatsby. Click through to see all the pictures from a big, busy week!

The Cannes Film Festival kicked off on Wednesday and the South of France has officially been flooded with celebrities. Carey Mulligan and Leonardo DiCaprio kicked off the festivities alongside Julianne Moore at the Opening Ceremony and The Great Gatsby premiere on Thursday. Meanwhile, Emma Watson was in awe of the fanfare when she took her own trip down the red carpet at The Bling Ring premiere yesterday. The action wasn't only on the red carpet as Rooney Mara proved when she attended a Calvin Klein bash alongside Harvey Weinstein on Thursday evening. Other stars like Justin Timberlake, Isla Fisher, Nicole Kidman, and Octavia Spencer have also been getting in on the Cannes fun this week. Be sure to check back for more Cannes Film Festival photos as they come in!

It may have been raining on the red carpet, but that did not stop our favourite stars from attending the premiere of The Great Gatsby at the opening ceremony to this year's Cannes Film Festival. From Carey Mulligan's sleek and streamlined Dior Haute Couture gown to Cara Delevingne's ultra-sexy body-con number from Burberry, these chic starlets weren't afraid to fete this year's fest with a level of glam that could only be surpassed by Jay Gatsby himself. A look at all of these gowns and more, here, in the gallery.

It was a big night in France as the Cannes Film Festival kicked off with the opening ceremony and the premiere of The Great Gatsby! Leonardo DiCaprio, Carey Mulligan, Joel Edgerton, Isla Fisher, Elizabeth Debicki (in Alex Perry) and Tobey Maguire all hit the red carpet after dressing up for a photo call to promote their film, which is at the festival out of competition, earlier yesterday. Cindy Crawford also showed her support in a white Roberto Cavalli gown while Julianne Moore, Freida Pinto, and juror Nicole Kidman walked the red carpet as well — be sure to check out all the glamorous looks from the Great Gatsby premiere.

They aren't the only stars descending on the French Riviera, since Justin Timberlake, Christoph Waltz, Kirsten Dunst and others have already arrived to take part in the film festival fun.

Leonardo DiCaprio suited up to join his The Great Gatsby leading lady, Carey Mulligan, to kick off the Cannes Film Festival with a glamorous photo call for their film yesterday. Leo and Balenciaga-clad Carey were joined by the rest of their co-stars, Isla Fisher, Tobey Maguire, Joel Edgerton, Elizabeth Debicki, as well as the film's director, Baz Luhrmann, as the annual festival got under way in the South of France. It was a busy day for the Gatsby crew, who also participated in a press conference to discuss the film that opened in the US last Friday (it opens in Australia on May 30). The Great Gatsby boasted impressive numbers in its first week, raking in $51.1 million from its US debut.

Leo and his long-time friend Tobey Maguire were reunited at the festival after pairing up earlier this week in NYC. Tobey showed his support at Leonardo's Christie's auction, which raised $35 million to benefit environmental and wildlife conservation efforts, a cause that is backed by the Leonardo DiCaprio Foundation.

The Cannes Film Festival opens tomorrow, but celebrities are already making their glamorous French Riviera entrances. Nicole Kidman shimmered onto the scene today, and Steven Spielberg greeted the crowd before heading into a photo call for the festival's jury panel. Cannes first-timer Emma Watson touched down at Nice airport earlier in the day, as did Leonardo DiCaprio.

The festival will start off with a 3D showing of Baz Luhrmann's The Great Gatsby tomorrow and will showcase other highly anticipated films like Ryan Gosling's Only God Forgives and Steven Soderbergh's Behind the Candelabra, starring Michael Douglas and Matt Damon. The international movie madness will run for 12 days and finish on May 26 with awards hand-selected by this year's jury.

Leonardo DiCaprio teamed up with Christie's to co-host the 11th Hour Auction in NYC last night. It was a successful event for Leo since the auction reportedly raised $35 million to benefit environmental and wildlife conservation efforts, almost doubling the goal of $18 million. He had the support of his long-time friend and Great Gatsbyco-star Tobey Maguire, who put in a winning bid on one of 33 pieces of contemporary art. Leo contributed something from his own art collection, a print called "Ocean V" by well-known photographer Andreas Gursky. Also out for the evening were Bradley Cooper, Mark Ruffalo and Salma Hayek.

It was Leonardo's second art-inspired outing in as many days, since he also made an appearance at the Brant Foundation Art Study Center's Andy Warhol showing in Greenwich, Connecticut, on Sunday. He'll be switching gears from art to film in the coming days, though, when he debuts The Great Gatsby in Cannes later this week.

It's been a huge week for celebs this week, with the 2013 Met Gala dominating the agenda for most, and movie screenings entertaining everyone from Miranda Kerr Carey Mulligan and Leo DiCaprio. Jennifer Lawrence and Sarah Jessica Parker shared a funny moment on the red carpet at the Met Ball, while Beyoncé's dramatic arrival sent the photographers' flashes into overdrive. Blake Lively got back to business after a long break from the spotlight (those legs look longer than ever!), and Baz Luhrmann was flanked by his stars at a special showing of The Great Gatsby. Keen to see more? Come this way!

The Great Gatsby finally comes out this month (May 30), and we couldn't be more excited for Baz Luhrmann's adaptation of the novel, starring Leonardo DiCaprio as the title character. We have a pretty good idea of what to expect from the many trailers that have come out and the leaks of the soundtrack, and if you can't get enough, good news: here are lots of pictures. Click through to see 60+ photos from the movie, including looks at each character in costume, shots of the amazing, eye-popping sets, and even a few behind-the-scenes shots.

There's a lot more going on in The Great Gatsby than just pretty cinematography and A-list actors like Leonardo DiCaprio and Carey Mulligan dressing up in period costumes. After recently attending the film's press conference in NYC, we learned a great deal about the highly anticipated new film.

Although The Great Gatsby doesn't hit cinemas until May 30, Leo, Carey, Isla Fisher, Tobey Maguire, director Baz Luhrmann, and costume director Catherine Martin chatted ahead of the release about the making of the project and how difficult it was to translate one of the most famous American novels into a film that modern-day audiences would want to see.

Read on for the five key points we learned from the press conference, including how Leo himself relates to the infamous Gatsby!
