The 24-year-old actress, who portrays Anastasia Steele in the steamy film adaptation of Fifty Shades of Grey, was photographed filming a scene on Sunday, Dec. 8 in Vancouver.
Johnson was sporting a layered schoolgirl look, wearing a flower patterned blouse, a baby blue sweater, long blue coat, a bright blue skirt, black tights and black boots. Her hair was styled in a ponytail and she was also toting around some books.
The blond beauty, who has some darker locks for the role, was making her way towards a building with the sign "Grey Enterprises," which refers to Christian Grey's business company.
Johnson is the innocent and beautiful college student turned recent graduate, who falls for Dornan, the handsome copper-haired entrepreneur. His obsession with S&M is eventually revealed and he asks her to be his submissive lover. But that's the tame version of the erotic romantic story, of course.
The star is working hard to stay in shape for all her time in the Red Room of Pain, and it seems that she has adopted the latest Hollywood diet trend: juicing.
Johnson and director Sam Taylor-Johnson have been ordering juices from The Juice Box, an organic cold-pressed raw juice company based in Vancouver.
"They order the organic cold-press juices. They love them. They have a standing order for them," an insider exclusively told E! News, adding that the pair "are not doing a cleanse and are basically drinking a couple each day."
(E! and Universal Pictures are both part of the NBCUniversal family.)
