Lohan's Sister Debuts On Silver Screen

Hollywood actress Lindsay Lohan is helping her teenage sister prepare for her silver screen debut later this year.

Ali Lohan, 14, will play "a popular high school senior" in an unnamed movie, according to People.com.

And the youngster has turned to her older sister for acting advice.

Ali tells Teen Vogue, "I grew up watching Lindsay. It made me want to do what she does. Just the whole vibe. Being there, being on camera, or onstage."

The film is based on the pre-teen book series Mostly Ghostly written by R.L. Stine, which centers on an 11-year-old boy who befriends two ghosts.
