Margot Robbie has just made her Cannes 2019 red carpet debut.

Appearing alongside co-stars Brad Pitt, Leonardo DiCaprio and director Quentin Tarantino, the 28-year-old actress dazzled in a Chanel, monochrome, sequinned babydoll look. She was just this week announced as Chanel's fragrance ambassador.

The ensemble consisted of a soft pink, sequinned babydoll style top, worn over sequinned black trousers and the actress paired the look with a black choker, black mules and tousled blown-out hair.

Arguably this year's most highly anticipated film, the Quentin Tarantino romp Once Upon A Time...In Hollywood features an incredible talent line-up, with Brad Pitt, Leonardo DiCaprio and Margot Robbie in starring roles.

A little bird also told us that the film nearly didn't make it to the Cannes Film Festival this year, because post-production on the epic wasn't actually finished.

In fact, it almost never got made at all. In an interview with Esquire, Tarantino explains that he spent five years writing it as a novel before he ' let it become what it wanted to become.'

Luckily for everyone though, the screening went ahead and the stars flew in for the celebration. They will presumably stay on for this week's amFar gala too.
