Margot Robbie received her first-ever Oscar nomination yesterday for her portrayal of Tonya Harding in I, Tonya. The Australian star is now in the running for Best Actress against Sally Hawkins (The Shape of Water), Frances McDormand (Three Billboards Outside Ebbing, Missouri), Saoirse Ronan (Lady Bird), and Meryl Streep (The Post).

Robbie was in her home country for an I, Tonya premiere when she heard the news. Her younger brother, Cameron Robbie, took to Instagram to document the special moment, which included smiles, close friends and plenty of drinks.

He also shared a photo of with Margot in a celebratory embrace. “There’s nothing I could say that articulates how proud I am of this one #whatamoment #academyawardnomaninee! [sic]” he said of his sister.

Robbie spent months of preparation for her role as the disgraced figure skater, according to Rolling Stone. She rigorously trained in skating (with Nancy Kerrigan’s former choreographer, ironically enough), perfected Harding’s odd accent (“It was entirely bizarre to me,” Robbie told Rotten Tomatoes) and underwent drastic physical transformations to portray the athlete over 29 years.

“I watched for about six months every single thing, every bit of skating, every bit of interview, every documentary, I played it on my iPod at night … I had her face, like, painted on the inside of my eyelids and her voice just constantly in my head,” Robbie told Rolling Stone of her prep. It looks like that all paid off.

Robbie’s co-star Allison Janney, who plays Harding’s mother, is also nominated for an Oscar, for Best Supporting Actress. Janney has been getting a lot of love this awards season after already winning a Golden Globe and SAG Award for the role. (Cymbalta)
