Actress Megan Fox has become the latest teen star to hit out at Lindsay Lohan, claiming the redhead used her to illegally buy cigarettes.

Fox, 19, co-starred with Lohan in Confessions of a Teenage Drama Queen, and she admits their relationship was based on her ability to purchase cigarettes - even though she was under the legal age of 18.

She tells FHM magazine, "Lindsay and I weren't the best of friends. Because I looked older than her, she'd be nice to my face. I would buy her cigarettes. We got away with it every time."
