The Australian actress is in the French city for the annual film festival to promote her new movie, Once Upon a Time in Hollywood

MARGOT Robbie showed off her diving skills in a white one-piece while enjoying some down time in Cannes.

The Australian actress is in the French city for the annual film festival to promote her new movie, Once Upon a Time in Hollywood.

And while she learned how to skate for her Oscar nominated turn in I, Tonya, Margot proved she is also pretty talented at diving.

Wearing a one-shouldered white swimsuit, the 28-year-old also showed off her trim figure as she made a splash at Eden Roc.

After clambering up some steps to the top, Margot dived off, her feet pointed and her back straight.

Her outing comes after her new movie had it’s premiere at the Cannes Film Festival.

Margot joined her co-stars Leonardo DiCaprio and Brad Pitt on the red carpet, as well as director Quentin Tarantino.

The star decided to forgo a sweeping gown in favour of black sequin trousers and a white sequin smock style top.

The garment featured a black sequin trim and the Australian actress added a pink rose and a black choker to complete her look.

This is the second time Oscar nominee Margot has starred with Leo, after the pair played husband and wife in 2013’s Wolf of Wall Street.

Once Upon a Time in Hollywood is set in 1969 and tells the story of a television actor and his stunt double as they negotiate their way through the film industry, trying to make a name for themselves.

The picture also stars Kurt Russell, Dakota Fanning, Al Pacino and late actor Luke Perry.
