Kristen Stewart & Robert Pattinson in '50 Shades of Grey'I'm pretty positive that nothing matters in Hollywood right now besides the Fifty Shades movie. Every actor under the sun has had their name tossed into the ring to play Fifty Shades of Grey's Christian Grey and Anastasia Steele, including Hollywood IT couple Robert Pattinson and Kristen Stewart. It's only natural, really. I mean -- whoever takes on the roles needs to have crazy chemistry. Why not a REAL life couple?

Of course, nothing's a done deal yet. The latest goss? Apparently Rob is all "WTF" over the idea that hottie Ian Somerhalder is being considered. A source told National Enquirer that "the thought of Kristen doing outrageously intense, naughty, and kinky scenes with any guy, let alone Ian -- another handsome vampire -- is making Rob nuts." 

Holy drama in the vampire world. I get it, Rob's supposedly not keen on watching his main squeeze get busy with someone else. I've gotta come out and say this, though: I think it could be for the best, Rob.

I've gotten used to seeing both Rob and Kristen in different roles on screen -- I loved Kristen in Snow White and the Huntsman. But together? I just believe that no matter how much time goes by, when Rob and Kristen are on the big screen together, they will always remind fans of Edward and Bella. I'm just not so sure if that's what that the future director of Fifty Shades wants for the film.

It's not that I don't think that the duo would be great in it. In fact, I think either one of them would handle the respective roles wonderfully. Mmm, the thought of Rob shirtless makes me sweat a little. Regardless, I just don't think it's right.

Ian and Kristen, though? Holy smokes! Knowing that working with Ian allegedly makes her boo totally heated would probably pump up the heat under the sheets. Helllooooo sexual tension at its best. Sounds Fifty Shades-tastic. 

Who do you want to see in Fifty Shades?
