On Instagram, pop star Beyonce for the film adaptation of the best-selling novel, "Fifty Shades of Grey."

While the trailer for "Fifty Shades of Grey" is slated for release on Thursday, July 24, Beyonce decided to kick off the promotional campaign a few days earlier.

These first 16 seconds of footage don't reveal much, other than a fleeting glimpse of a visibly very eager Christian Grey and what must be the knees of his young mistress Anastasia Steele, soundtracked by an excerpt from Beyonce's song "Crazy in Love." The singer did not reveal whether she is the one heard sighing and breathily singing a few lyrics in the teaser.

Adapted from the international best-selling erotic novel of the same name, "Fifty Shades of Grey" is one of the most anticipated films of 2015. This Thursday, fans of the book will be able to see more footage from the feature in the first trailer. The video will be followed by an interview with Dakota Johnson ("Need for Speed," "The Five-Year Engagement") and Jamie Dornan ("The Fall"), the two stars of this S&M love story between a billionaire and a young college student.

Initially scheduled for release on August 1, 2014, film was ultimately pushed forward and will arrive in US theaters on Valentine's Day, February 14, 2015. The film is directed by Sam Taylor-Johnson.
