Dakota Johnson takes juices to stay hydrated during filming?

Los Angeles: Actress Dakota Johnson has reportedly been consuming a lot juice to stay hydrated during the filming schedule of `50 Shades of Grey`.

The director of the film Sam Taylor-Johnson and Dakota, 24, who plays Anastasia Steele in the big screen adaptation of E L James` erotic novel of the same name, have been ordering juices all day long, reported E! Online. "They order the organic cold-press juices. They love them. They have a standing order for them. They are not doing a cleanse and are basically drinking a couple each day," a source said. "This will be a tough movie to film. They are sometimes starting as early as 6:30 am and there are long hours. The juices help them feel great and maintain a high nutritional intake. They energise you and you don`t get the same crash with sugar or coffee. It is a more sustainable energy level," the source added. The movie in which Jamie Dornan stars as Christian Grey, would be releasing on February 13, 2015.
