The I, Tonya star found out during an appearance on ABC News' Popcorn With Peter Travers on Wednesday that she had been nominated for Outstanding Performance by a Female Actor in a Leading Role at the 2018 Screen Actors Guild Awards for playing Tonya Harding in the new biopic, and couldn't help but break a smile wide across her face.
"This is already too good to be true," the 27-year-old actress beamed. "When you make the film, you're so worried about actually pulling it off and making it ... "That you kind of forget about the part where you show everyone, and wait to see what they think. It's scary."
Robbie was nominated alongside co-star Allison Janney, who is up for Outstanding Performance by a Female Actor in a Supporting Role.

The nod is another reason to celebrate for the Australian star, who also earned a 2018 Golden Globe nomination earlier this week.
"Cheers to the HFPA for giving us something to celebrate this morning! THANK YOU ??⛸? #itonya#goldenglobes," Robbie captioned a champagne-toasting video on Instagram on Monday.
ET spoke with Robbie last month at the New York City premiere of the film, which explores the tragic backstory behind the disgraced figure skater, about playing such a well-recognized person and showing audiences a take they may not have been exposed to previously.
“It’s scary playing a real-life person especially when that person is still very much alive,” Robbie told ET. “Everyone has a recollection of what they think happened, and it’s kind of fun and interesting to show a different side of that story and maybe a side to Tonya that people weren’t expecting to see.”
