They may play a combative mother-daughter duo on screen, but in real life, Allison Janney and Margot Robbie are very much in awe of each other.
ET's Nischelle Turner spoke with both stars at the Hollywood Film Awards in Los Angeles on Sunday, where their film, I,Tonya, was honored with the Hollywood Ensemble Award, as well as Best Supporting Actor Award for Janney.
Janney had nothing but high praise for Robbie, who not only stars as controversial figure skater Tonya Harding in I, Tonya, but also served as a producer on the film.
"I'm in complete awe of what she's done," the Mom star said of Robbie and her work ethic. "She's not stopped working since we did this movie back in February. She and her husband [Tom Ackerley], and LuckyChap [Entertainment, the couple's production company], they're producing so many movies."
"I saw some of the pictures online because I had to do an interview with her for a magazine, and I was just floored by her," Janney said.
The West Wing alum also admitted that Robbie looks amazing out of costume and make up as well. "She is one of the most beautiful women on the planet, she really is," she gushed. "I can't stop looking at her pore-less skin and just like, salivating."
For her part, Robbie said she was thrilled for the movie to be honored so early in the awards season, and for the chance to work with co-stars like Janney and Sebastian Stan as both a producer and an actor.
"I mean, I feel like we hit the jackpot," the 27-year-old said of the casting process. "Not only brilliant, talented actors, but wonderful people and we all got along so well and we had so much fun. That, in itself, in my mind, is the best thing that could have happened, but to be recognized and get an award for it at the end of the day, is just icing on the cake."
The star also dished on her insanely busy work schedule that Janney had raved about.
