Brie Larson finds it "difficult" to see herself with make-up on.
The 'Room' actress doesn't feel like herself when she's glammed up and tries to avoid her reflection whenever she can.
She said: "When I have make-up on, I have a very difficult time looking in the mirror.
"I think it just looks bizarre to me. Every time I go to the bathroom today, I wash my hands looking down.
"Otherwise you go, 'Wah! I don't know what that face is. It doesn't look like me at all."
And the 26-year-old beauty finds it particularly "terrifying" if she catches sight of herself in a magnifying mirror.
She admitted: "I have this weird thing about not liking to see my face bigger than it is, if I were to be looking in a mirror."
Because of that, Brie can't bring herself to watch her movies in the cinema.
She said: "I find it terrifying."
Though the 'Free Fire' actress never feels nervous when she's working, she does get anxious once filming wraps.
She explained to Total Film magazine: "I never get nervous with the prep and I don't get nervous with the shooting.
"I only get nervous once it's done and then there's nothing I can do about it anymore."
