Another week bites the dust, and what a packed seven days it has been! Things kicked off with a lavish royal wedding in Sweden, when beautiful Princess Madeleine married her American banker partner Chris O'Neill. Princess Mary and Prince Frederik were among those in attendance, with Mary wowing in a bright coral dress. Also wowing fans? Jason Segel, who stepped out in Hollywood clutching the hand of his new girlfriend, who happens to be Australian. Who is she?

Katie Holmes, Naomi Watts and Anna Kendrick teamed up at Coach's Summer Party on the High Line in NYC yesterday. The three women were joined by Nashville star Connie Britton, Revenge's Joshua Bowman and model Chrissy Teigen as they mingled with New Yorkers at the park. Katie is currently filming her new project, Mania Days, in the city and she caused quite a stir on set a few weeks ago when she was spotted filming love scenes with co-star Luke Kirby out in public. Meanwhile, Naomi has been playing social butterfly in the Big Apple while her long-time love, Liev Schreiber, finishes up filming for his new project, Ray Donovan, in LA. Naomi hit up Stella McCartney's Resort 2014 presentation with friends Cameron Diaz and Kate Bosworth on Monday and joined forces with Sienna Miller at a charity event last week. She has big news to share today as the new trailer for Diana, her film about the life of Princess Diana, was released online.

This week's best dressed list was owned by Australian ladies. Nicole Kidman was the epitome of an iconic movie star, wowing the crowds at Cannes with her blue, red, black and white L'Wren Scott dress — that she went with the designer is no surprise, but her dress was a bold choice that really paid off. Also rocking the prints was Nicole's good friend Naomi Watts, in a floral Dolce & Gabbana tea-length dress, while Jess Hart and Megan Gale opted for black dresses with pretty details making all the difference.

The Swiss watch brand IWC Schaffhausen gathered stars in France for the Cannes Film Festival in the town of Antibes last night for its For the Love of Cinema party. The location was the luxurious seaside Hotel du Cap-Eden-Roc, which made for a picturesque night. Rooney Mara, Naomi Watts and Karolína Kurková were among the famous women who hit the red carpet wearing timepieces from the brand, as did actor Christoph Waltz and race car driver Lewis Hamilton. The group was treated to a performance by Jamiroquai's Jay Kay and dinner inside the hotel's restaurant.

Wearing a long-sleeved leather Balmain dress, Karolína discussed her bold choice and said, "It's not short!" She also revealed that her travels to Cannes were partially for work and partially for a family holiday with her husband, Archie Drury, and their son, Tobin. Naomi, meanwhile, wore a chic floral gown from Dolce & Gabbana. She told us on the red carpet that when in the South of France, she dresses the part. Though her day-to-day choices aren't fancy, she ups the fashion ante even more than usual for premieres and events at the festival's iconic Palais.
