“Fifty Shades of Grey” is nearly a year away from releasing the highly anticipated film based on author E.L. James’ erotic books. But until then, what are die-hard Christian Grey and Anastasia Steele fans supposed to do? Well, stop twiddling your thumbs and use those babies to start scrolling around Twitter, because James may have just leaked a casting spoiler on her very own social media account.

The author is no stranger to tinkling fans’ fancy with her teasing tweets, her latest one being a casting rumor regarding the gorgeous Katie Cassidy. “Katie Cassidy… Isn’t she flexible?” James captioned the photo of the American actress stretching her leg across her chest. Cassidy is known for her roles in "Arrow," “Melrose Place,” “Gossip Girl,” “Taken,” “Monte Carlo” and “Supernatural.”

Could this Instagram picture actually be a “Fifty Shades of Grey” casting hint? We happen to think so! Why else would Katherine “Katie” Cassidy travel across the pond? We doubt she trekked all the way to James just to share a drink.

Based on Cassidy’s stunning looks and cascading brunette locks, we have to confess that she and Dakota Johnson, who is playing the coveted role of Anastasia Steele, look eerily similar. And maybe there’s a reason for that! Could Cassidy be taking on the “Fifty Shades” character Leila Williams?

Leila Williams was romantically involved with Christian Grey for two and a half years before Anastasia came into the picture. After a submissive relationship with the handsome protagonist, Leila left Christian for her husband. Eventually, Leila has an affair with her lover named Geoff, who gets killed in a car crash later down the line. After his death, Leila has a mental breakdown. Which results in some eye-widening moments in the novel.

Reports point out that Christian may have a certain “taste” in women. With brunette tresses and “brown, like bourbon” eyes, Anastasia is even shocked by how much she and Leila look alike.

Do you think Cassidy will be playing the role of Leila Williams in the “Fifty Shade of Grey” movie adaptation of E.L. James’ book? Let us know what your theories are in the comments section below.
