'Blue is the Warmest Color,' a French love story about two young women, has won the Palme d'Or at the Cannes Film Festival.

Tunisian-born director Abdellatif Kechiche's romantic film won rave review in Cannes but shocked some critics with its graphic and non-simulated sex scenes.

Variety magazine said it contained "the most explosively graphic lesbian sex scenes in recent memory".

Adele Exarchopoulos stars in the film as a 15-year-old girl whose life is changed when she falls in love with an older woman, played by Lea Seydoux.

In a surprise move, the jury awarded the prize to three people, the director and his two actresses.

Kechiche, Exarchopoulos and Seydoux clutched each other as they accepted the award, which is considered one of cinema's highest honors.

"You made a lot of people happy," Kechiche said as he turned to the nine-member jury, which was headed by Steven Speilberg and included Nicole Kidman, director Ang Lee and Oscar-winner Christoph Waltz.

An American film directed by brothers Joel and Ethan Coen won the festival's second-highest honor, the Grand Prix.

The film, 'Inside Llewyn Davis' stars Justin Timberlake and Carey Mulligan in the story of New York's 1960s folk scene.
