Lindsay Lohan's younger sister Ali is to make her feature acting debut in a film based on RL Stine's pre-teen books 'Mostly Ghostly'.
A spokesperson for the 14-year-old said: "Ali Lohan, 14, has been cast in the film as a popular high school student, emulating the type of role played by sister Lindsay in the 2004 film comedy 'Mean Girls'."
The 'Mostly Ghostly' series tells the story of a boy with two ghosts living in his bedroom.
The film is due out later this year.
