Margot Robbie, Leonardo DiCaprio and Brad Pitt are bringing major star power to the 72nd annual Cannes Film Festival. 

The trio, who star in the highly anticipated Quentin Tarantino-directed film, Once Upon a Time in Hollywood, slayed the red carpet at the movie's screening on Tuesday. 

Robbie was gorgeous in a beaded tunic from Chanel adorned with a bow and pink camellia flower, paired with beaded pants and pointed-toe black shoes. For glam, the Australian beauty let her blonde tresses down, complemented by soft smoky eyes and a glossy pink lip. 

DiCaprio, in Giorgio Armani, and Pitt coordinated in similar black tuxedos and bow ties. Tarantino looked dapper in a black suit and tie.

Dakota Fanning, who also stars in the film, looked regal in a stunning pale pink Giorgio Armani Privé gown accented with a light yellow sash and Chopard jewelry. Her little sister, Elle, channeled 1950s glamour in a Dior ensemble of a voluminous silk blouse, a full navy blue tulle skirt and a wide-brimmed raffia hat with an Agent Provocateur corset.

Elle had a little bit of a scare at a dinner Monday night when she fainted while she was seated next to Dakota, Variety reported. The Teen Spirit actress addressed the incident on Instagram saying, "it's all good!!"
