Isla Fisher

Courteney Cox's 49th birthday celebrations in LA over the weekend were a star-studded affair. She was joined by her famous pals, Isla Fisher, Busy Philipps, Laura Dern and Jennifer Meyer, who is Tobey Maguire's wife, for festivities at Giorgio Baldi restaurant. Courteney took to her Twitter account to document the fun surrounding the special occasion, which would not be complete without her daughter, Coco Arquette. She shared a photo of herself and her daughter during the party writing, "Every birthday is perfect with my favourite girl." Courteney also shared a group shot of pregnant Busy, Isla, Lauren and Jennifer with the caption, "Dancin with my girls." Busy sent her wishes on Twitter too writing, "Happy Birthday to Courteney Cox! One of the greatest ladies I know!"

Amy Poehler and new boyfriend Nick Kroll made their first public debut when they attended AFI's Lifetime Achievement Award tribute to Mel Brooks in Hollywood yesterday. The two stars have reportedly been dating since April, but they have been friends for years before they got romantic. Amy and Nick met at the Upright Citizens Brigade, and Nick recently admitted that he always had a crush on her, saying, "There are people you have crushes on because they’re physically attractive, and there are people you just have comedy crushes on, and they’re constantly intersecting. I had comedy crushes on men and women at [UCB]. And I think it’s fair to say that everyone who meets Amy has a crush on her."

Amy and Nick weren't the only funny couple at the bash, which included an appearance by Sacha Baron Cohen and Isla Fisher, who recently co-starred with Amy's ex-husband, Will Arnett, in the new season of Arrested Development. Other guests included Zach Galifianakis, who was hot off an international press tour for his latest film, The Hangover Part III, Sarah Silverman, and Larry David, who attended the party with his daughter Cazzie. Despite all the A-list comedians floating around the event, all eyes were on honoree Mel, who got a big kiss from Sacha when he spotted him backstage.

What a week it's been! So much of this week's action has taken place in Australia, and it's been non-stop since the get-go. Baz Luhrmann brought his The Great Gatsby to town on a very rainy Wednesday night, and with him at the premiere were the film's stars Carey Mulligan, Tobey Maguire, Joel Edgerton and Elizabeth Debicki, to name a few. The latest crop of CLEO Bachelors were announced, David Jones celebrated it's 175th birthday with a host of stylish stars like Megan Gale and Rachael Finch, and honorary Aussie Joel Madden went on a coffee run in Sydney with his adorable family. Elsewhere, Cannes kicked on and Kate Middleton made a sunny appearance at a royal garden party. Click through to see it all now!

After an exciting few days in France for the Cannes Film Festival, Isla Fisher was back in NYC today for the premiere of her new movie Now You See Me (out Aug. 29). She was joined by some of the esteemed actors in the mostly-male cast, including Morgan Freeman, Michael Caine, Woody Harrelson, Jesse Eisenberg and Mark Ruffalo, who brought along his wife, Sunrise Coigney, and their three young children. In the film, Isla, Jesse, Woody and Dave Franco are a magic group act who steal money from corrupt business leaders and return it to their audiences during their acts. Meanwhile the FBI is trying to catch them and work out how they’ve been pulling off their daring heists.

Isla’s appearance in NYC today means she’ll be absent from tonight’s Sydney premiere of The Great Gatsby, which will still have a huge star presence thanks to Tobey Maguire, Carey Mulligan, Joel Edgerton, Elizabeth Debicki, and filmmakers Baz Luhrmann and Catherine Martin, along with a host of local talent.

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!

The Cannes Film Festival red-carpet events kicked off with The Great Gatsby premiere, setting a high bar for all the celebrity glamour to follow. Yesterday, Emma Watson and Freida Pinto furthered the A-list allure with arrivals at their respective premieres. Freida glowed in an embellished Sanchita gown as she made her way down the carpet at the Jeune & Jolie screening, while Emma traded her photocall style for black-and-white Chanel at the premiere of The Bling Ring.

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.

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.

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!

Between new haircuts, updated styles, slicked locks and lots of ombré, hair certainly stole the show in this week's celebrity beauty round-up. Nicole Richie set the pace with her first official appearance since she took a trip down fringe lane (hubby Joel Madden didn't notice — ah, men), while Kate Middleton mixed things up with wavier hair than usual (not to mention that pregnancy glow). But it wasn't all about hair. Isla Fisher totally stole the show at The Great Gatsby world premiere, thanks to her bright red lips and cats-eye liner — see that look and more when you click through!
