Lindsay Lohan may be stuck in rehabilitation for a few days longer but that isn't stopping her from thinking of various comeback moves. In fact, sources claim that the former Hollywood "It" Girl has got her eye on a certain role. Lohan is allegedly dead set on becoming Anastasia Steele for "Fifty Shades of Grey." Yet, here are five good reasons why Lindsay shouldn't be Ana.

Nothing says a big comeback than some S&M action on screen. This is what Lindsay Lohan is hoping for when she comes out of rehabilitation. The former Disney star wants to star as Anastasia Steele in the upcoming film adaptation of "Fifty Shades of Grey."

"Lindsay needs a big high profile role. She needs to be part of a movie everyone wants to see and thinks 'Fifty' is a role she would be perfect for. She has read the book several times and knows this is a character that she can play. She wants to be part of something iconic, something that will live forever like Harry Potter or The Hunger Games. Now, she thinks she has found it," explains a friend close to Lindsay.

Obviously, Lindsay would get a lot of attention for starring in the film but they won't certainly be good. Who could ever forget Lindsay's first comeback film, "Liz & Dick?" Apparently, things didn't work out for the film which had been called another "disaster."

"Lohan as Taylor was a bad idea in the dramatic sense, but it's pure genius both for marketing and for belly laughs and drinking games," states Goodman in his review for "Liz & Dick."

Fans of "Fifty Shades" would also highly agree that Lohan is too "used" to play the innocent role of 21-year old Anastasia Steele. Check out the slideshow to read five reasons why Lindsay Lohan should not play Anastasia Steele.
