Margot Robbie comes as 'Superstar Barbie'

Margot Robbie dressed as "Superstar Barbie" at the ceremony.

The 33-year-old actress - whose red carpet wardrobe while promoting the 'Barbie' movie over the summer was inspired by iconic looks sported by the Mattel doll over the years - dazzled on the red carpet in a hot pink sequinned Armani gown, which she teamed with a similar-hued mesh shrug.

Variety and 'Entertainment Tonight' red carpet host Marc Malkin jokingly asked her: “What made you decide to wear pink today?”

Margot - who was nominated for the Best Performance by a Female Actor in a Motion Picture – Musical or Comedy prize for her titular role in the film - laughed: “I don’t know, I just woke up and thought maybe this would be appropriate tonight. This is Armani and it is Superstar Barbie from 1977.”
