Lindsay Lohan has yet to sign her contract to play the late Elizabeth Taylor in a new movie.

The Mean Girls actress is set to play the star - who died of congestive heart failure last year - in a forthcoming film for the Lifetime channel, and despite shooting due to start in just a few weeks in Canada she has not yet officially signed on.

"Lindsay is planning on signing the contract this week if all proceeds as scheduled. Lindsay is excited at the prospect of being back on set again. The major parts of the contract are in place and all that is needed now is signatures of Lindsay and the producers of the project," a source said.

Recently it was claimed producers behind the movie were concerned about her ability to tell the truth after conflicting reports of an alleged altercation with Marisa Dugas at the Chateau Marmont hotel.
