The American actress is famed for her roles in Dan in Real Life, The Tenth Circle,Avalon High and Scream 4. Since appearing in a range of movies, Britt has attended many red carpet events.
However, the 21-year-old star is none the wiser when it comes to beauty and style.
"I'm not even a little bit talented at the red-carpet make-up thing, but recently I did learn how to give myself dramatic-looking eyes and how to contour my cheekbones," she revealed.
Although Britt is laid back when it comes to her day-to-day beauty regime, she does love her on-screen transformations. The stunning star can't believe how make-up and hair styling can alter the look of someone so radically.
"I'm very low-maintenance, but I had to get bangs and extensions for The First Time," she explained in an interview with Teen Vogue.
"I'd never looked that glamorous before - and I felt like a completely different person!"
Britt is a self-confessed "tomboy". However, she makes sure she takes care of her skin when she's partaking in outdoor pursuits.
"I'm very fair, so when I'm hitting the waves, I always wear sunblock. For every day, I really like Murad skin-care products," she said.
As for her every day cosmetic essentials, Britt loves Maybelline New York mascara and says that "drugstore mascaras are the best".
