The Fifty Shades of Grey trailer has about as many whips, ties, masks and smooches you'd expect for the movie version of the literary guilty pleasure, but it's also got one surprise for those daring to watch: Beyonce!
"Crazy in Love" got a serious makeover for the film's first big sneak peek, with the megawatt hit smoothing up and slowing down. Much like Bey and Andre 3000's take on Amy Winehouse's "Back to Black" for The Great Gatsby's soundtrack, "Crazy in Love" sounds like something you'd hear at a jazz club instead of the set-closing smash she typically delivers to a full stadium.
Watch the trailer in full for a clip of the song above, but head's up: there's a bit of BDSM action and it's probably NSFW. (Unless you're employed by the real-life Christian Grey, that is.)
