Mean Girls fan Margot Robbie
Margot Robbie recited lines from 'Mean Girls' to Tina Fey.
The Australian actress is a big fan of the teen comedy and couldn't resist quoting the script at her 'Whiskey Tango Foxtrot' co-star, who wrote the screenplay for the 2004 movie.
She said: "I love 'Mean Girls'. I can recite most of the lines and sometimes I would do that in front of Tina until I remembered that she actually wrote the script."
The 25-year-old beauty was initially "intimidated" by Tina, but the 'Saturday Night Live' star quickly put her at ease.
She said: "I have to admit it is intimidating when you know you're working with one of the greatest sketch comedians and comedic actresses of all time.
"Tina is such a wonderful person, so generous and friendly, that she made it very easy for me to feel comfortable.
"She's so talented at what she does that when you're on the set she inspires you to lift your game."
Margot plays a war reporter in the true-life tale and doesn't think it is a job she could do for real.
She told Britain's HELLO! magazine: "I think I could handle the partying side of being a war correspondent but I couldn't imagine what it would be like to live in a war zone on a daily basis."
