A sneak peek of the "Fifty Shades of Grey" emerged online through an unlikely source. Singer Beyonce posted a 15-second video clip of the much awaited movie adaptation in her Instagram account.

Last weekend, Beyonce shared a teaser trailer of "Fifty Shades of Grey" and garnered hundreds of thousands of likes, which is treated as a glimpse of the trailer coming on July 24. Beyonce's posting hinted that she is included in the film's soundtrack.

The video showed Christian Grey looking out of a window. A woman was also seen with her dress being lifted. The short video clip soundtrack was the sexier and slower rendition of Beyonce's song, "Crazy I Love."

This is far from the reports that claimed that the erotic aspects of the trailer were when Anastasia Steele was wearing a blindfold, Christian's hand was resting on her thigh, and the shot of the Red Room's door's opening.

Meanwhile, the official trailer of "Fifty Shades of Grey" will be released on July 24. This is confirmed by the author of the erotic trilogy.

"Hold on to your hats folks. You'll get your first look at the FSoG movie trailer on July 24. I've had a sneak peek and WOW! #WeAimToPlease," author of the book E.L. James tweeted.

The filming of the "Fifty Shades of Grey" wrapped up last February. However, the release of the trailer was allegedly delayed. According to previous reports, the trailer is more romantic than sexy.

Christian Grey is played by Jamie Dornan and Anastasia Steele is played by Dakota Johnson. The movie also stars Victor Rasuk as Jose, Eloise Mumford as Kate, Marcia Gay Harden as Dr. Grace Trevelyan Grey and Luke Grimes as Elliot Grey. Sam Taylor-Johnson is director, and James is one of the executive producers.

"Fifty Shades of Grey" is set to hit the theaters on February 13, 2015.
