Dakota Johnson loves getting tied up!

The 50 Shades of Grey actress appears in basically nothing (but ropes) for The Weeknd's newly released video, "Earned It (Fifty Shades of Grey)," for the upcoming S&M-tastic film. BTW: if you have kids around you -- you probably should cover their eyes -- because this is pretty SEXXY.

The video features the band's frontman Abel Tesfaye as he sings to a back drop of scantily clad women. Eventually, a writhing Dakota, who plays Anastasia Steele in the highly anticipated film, as she's suspended overhead by ropes. All of you dom/submissive types are probably going gaga over this!

So how does she get that fit form? By working out of course! The 25-year-old star hit Winsor Pilates on Wednesday afternoon in Los Angeles. We have a feeling that the Melanie Griffith and Don Johnson's daughter is gearing up for her upcoming parade of press events for Fifty Shades of Grey, which unzips into theaters on Feb. 14.
