On the set of "Fifty Shades of Grey," Dakota Johnson has been getting into the role of Anastasia Steele by juicing.

E! reports that Johnson and director Sam Taylor-Johnson have a "standing order" for pressed juices in a Vancouver shop where they are filming scenes for the film.

According to E!'s source, Johnson and Taylor-Johnson are "not doing a cleanse and are basically drinking a couple each day."

So there you have it. Always good to know what it takes to look aesthetically-pleasing while participating in hardcore BDSM that has been equated to "mommy porn."

In a variety of photos snapped on set, it appears Johnson has been keeping up her fit figure and has also been questionably wearing Uggs, which we can only hope are not part of her costume.
