Lindsay Lohan has blamed "work stress" for the substance abuse problems that landed her in rehab last year.
The Mean Girls star, who spent last summer at a Utah rehabilitation center, also claims she used drink and drugs to escape from the emotional pain brought on by being estranged from her father Michael. Lohan, who reunited with her dad in rehab, says, "I had a lot going on in my life and that was a way of hiding from it."
