Here's how Hollywood's biggest stars are partying at the Cannes Film Festival

It's Cannes time again.

That is, when Hollywood's elite travel to the French Riviera for the industry's most glamorous event of the year, the Cannes Film Festival.

This year, things kicked off with the latest movie from Woody Allen, "Cafe Society," which stars Kristen Stewart, Jesse Eisenberg, and Blake Lively, among others. The premiere also put the sex-abuse allegations against Allen back in the spotlight.

The latest Jodie Foster-directed movie, "Money Monster," starring George Clooney and Julia Roberts, is also in the festival. As is the animated family movie "Trolls," with Justin Timberlake and Anna Kendrick lending their voices.

Below, see the stars as they walk the historic Cannes red carpet, and how they enjoy their time basking in the French Riviera.
