Robbie, fresh off her appearance at the Golden Globes in ‘Barbie’ pink, shook things up by opting for a gown from Italian fashion house, Valentino. The award-winning actress is a longtime ambassador for French designer Chanel, and often wears their designs at public events.

It comes after the I, Tonya star talked about how “frantic” she was to score the role of Nellie LaRoy in the Damien Chazelle-directed period dramedy, which hits cinemas in Australia on January 19.

“When I got the script for Babylon, I felt I had to do it. I’ve never felt that way about a script,” Robbie told W Magazine this week.

“I was frantic. At one point, I suggested showing up at the director’s house.

“When we eventually met, I said, ‘I have to play this character. She’s mine.’”

Robbie made headlines in December when she revealed she had suggested to Chazelle, 37, that her character kiss co-star Brad Pitt’s character. “When else am I gonna get the chance to kiss Brad Pitt?” she admitted to E! News.

Expanding on the revelation, Robbie added it was actually improvised – and left Pitt stunned.

“I actually improvised a kiss that wasn’t in the script,” Robbie shared.

“We were doing a party scene, and Nellie goes up to Brad Pitt’s character and Katherine Waterston’s character, and I was like, ‘F**k it. I’m just gonna kiss them and see what happens.’

“They were a little bit shocked. I don’t know if it made it into the movie.”

The scene in question did make it into the final cut.

Los Angeles-based Robbie is headed home to Australia in the coming days for the Babylon premiere in Sydney on January 16, alongside her co-star Diego Calva.
