50 Shades of Grey Movie Cast Rumors: Matt Bomer vs. Ian Somerhalder as Sexy Christian Grey, Kinkier Lyndsy Fonseca as Anastasia Steele Lover? [VIDEOS/POLL]

What do Matt Bomer and Ian Somerhalder have in common? They're both sexy, sweet, and devastatingly charming... oh, and they're both top fan-favorites to snag the kinky role of Christian Grey in the highly-anticipated film adaptation of E.L. James' "Fifty Shades of Grey!" But the big question remains... who should play Mr. Grey's erotic lover, Anastasia Steele? How about the "Young and the Restless" starlet, Lyndsy Fonseca? The stunning 26-year-old actress stars in several mock "Fifty Shades" trailers alongside Somerhalder and Bomer... do fans approve? Check out the steamy clips below and take the latest "Fifty Shades" casting poll to find out!

Somerhalder and Bomer continue to stir avid Mr. Grey buzz on the web... typically alongside Anastasia Steele fan-favorites Nina Dobrev and Alexis Bledel. The only problem is... the "Vampire Diaries" sweethearts just broke up, and Bledel doesn't seem too interested in pursuing the erotic role (especially since just getting engaged to Vincent Kartheiser). So how about "Nikita" babe, Lyndsy Fonseca? The pretty brunette hasn't gained too much Miss Steele recognition, but apparently some fans think she'd be perfect for the kinky part:

Fonesca is well-known for starring in several roles on television... "Young and the Restless," "Desperate Housewives," "How I Met Your Mother"... do fans think starring in "Fifty Shades" would be the perfect opportunity for Fonseca to make a name for herself in the movie bizz? She's originally from Cali and is of Portuguese and German decent... and she's beautiful!

So... what do "Fifty Shades" fans think?
