Johnson believes this might be because of her role in the 2015 film Fifty Shades of Grey, where she played a college graduate engaged in a sadomasochistic relationship with a young business magnate.
Despite the racy scenes in the movie, Johnson clarified that her private life does not reflect her on-screen character's interests. As an actor, she explained, she simply pretends to be someone else.
However, Johnson also acknowledged that many people tend to assume actors are similar to the characters they play.
Although she's currently single after breaking up with musician Matt Hitt last year, Johnson has been busy focusing on her acting career. She admitted that she sometimes feels lonely, but she enjoys spending her free time watching movies and reading books.
Ultimately, Johnson feels grateful for the solitude she has, and she's content to concentrate on her job rather than worrying about finding a partner.
