Rooney Mara

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 vacation 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.

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.

The fun wasn't over for the Met Gala 2013 attendees in NYC last night as they flocked to the Standard Hotel following the ball for the official afterparty at the Boom Boom Room. Madonna stripped out of her bum-baring Met Gala outfit and changed into a fishnet body stocking and black lacy lingerie to mingle with guests like Katy Perry, Allison Williams, and Frank Ocean. She wasn't the only star who made a costume change — Amanda Seyfried took off her gown and changed into a baggy black t-shirt to hit the dance floor with Frank. Meanwhile, Miranda Kerr met up with January Jones, Jennifer Lawrence arrived with Marion Cotillard, Gerard Butler mingled with Karolina Kurkova, andNicole Richie connected with Kirsten Dunst, and Mary-Kate Olsen snuggled with boyfriend Olivier Sarkozy. Mary-Kate and Olivier weren't the only couple at the late-night bash, as Jennifer Morrison was spotted holding hands with her Once Upon a Time costar Sebastian Stan and Kate Bosworth hugged Michael Polish.
