​Photos from the Cannes Film Festival's star-studded parties

The Cannes Film Festival is famous for many things – celebrity sightings, glamorous premieres, star-studded red carpets and so on – but its parties are truly legendary. Ever since Brigitte Bardot and Sophia Loren made a name for themselves on the French Rivera’s party circuit in the 1960s and '70s, the festival has boasted some of the most glittering and exclusive bashes of the year.

Cannes Film Festival: See all the red-carpet fashion

Cannes jury member Sienna Miller has been a busy bee at the festival this year, attending endless photocalls and continually wowing on the red carpet, but the 33-year-old has been dazzling during her downtime, too. With friends like Emily Blunt and supermodel Doutzen Kroes in tow, the actress attended a glitzy party hosted by Calvin Klein over the weekend (May 18).

Sienna shared a moment with The Devil Wears Prada’s Emily Blunt at the bash, as the pair warmly embraced upon spotting each other across the room. They rarely left each other’s side throughout the evening, the two moms no doubt enjoying rare quality time to catch up amidst their hectic schedules.

It wasn’t Sienna’s first party on the French Riviera – far from it. The in-demand actresses also attended an event hosted by The Hollywood Reporter and Swarovski, where she was seen mingling with the likes of Michelle Rodgriguez, Jane Seymour and Harvey Weinstein.

Meanwhile, at the De Grisogono Party, models Cara Delevingne, Chanel Iman and Karlie Kloss snuggled up to Derek Blasberg for a selfie. (They may be banned from the red carpet, but selfies are totally en vogue at after-hour gatherings!) They were joined at the celebrity-filled fête by Antonio Banderas, Adrian Brody, Robin Thicke and Natalie Portman, who was a vision in emerald-green gown by Lanvin.
