Lindsay Lohan's attempts to ditch her teen queen image have gone one step further - she has reportedly signed to star in John Lennon assassination movie CHAPTER 27.

The Mean Girls actress will star opposite actor Jared Leto, who will play murderer Mark Chapman, as an obsessed Lennon fan, reports US publication The Daily Variety.

It will be Lohan's second assassination movie - the actress is just beginning work on EMILO ESTEVEZ's BOBBY, which focuses on the assassination of ROBERT KENNEDY.
