Lindsay Lohan's father, Michael, has claimed that his daughter's first encounter with drugs took place when she was shooting rom-com 'Just My Luck' aged just 18.
The 2005 flick was the movie after which the 27-year-old actress' father Michael and his wife Dina legally separated, a split that hit the troubled actress hard, the Sun reported.
The 53-year-old told the publication that Lindsay was filming in New Orleans and he got a call saying that she had overdosed on cocaine.
He asserted that one of his daughter's assistants had given her the drug.
He told the tabloid that he was so angry that he got a gun from the house and planned to go to New Orleans to kill the assistant.
