TV executives have reportedly agreed to let Lindsay Lohan play screen siren  Dame Elizabeth Taylor in a new TV movie, as long as she keeps out of trouble.

The Mean Girls star was previously named as one of the frontrunners to play the late star in the Lifetime network biopic, Liz and Dick, which will focus on Taylor's love affair with Richard Burton.

Executive producer Larry Thompson revealed he was in talks with several young Hollywood stars, including Lohan and Megan Fox, about playing the legendary Oscar-winner, who died last year.

He said, "It's a very serious selection. It's like casting for Hollywood royalty."

Thompson has now decided to give the job to Lohan, as long as she sticks to the rules of her probation following a string of legal problems, according to Access Hollywood.
