LiLo 'guzzles 2 ltrs of vodka a day'
Lindsay Lohan has allegedly become so stressed by her worrying financial condition and her impending probation violation that she has started boozing heavily and sometimes downs as much as two litres of vodka a day.
According to sources, the 26-year-old actress, who has struggled with substance abuse in the past and even has a drinking under influence conviction under her belt, often begins drinking first thing in the morning, and continues drinking throughout the day, TMZ.com reported.
As for the Thursday morning NYC nightclub fight, 'The Parent Trap' star drank all day and showed up at the Bieber concert already smashed and continued to drink throughout the night.
Lohan's friends have given up trying to help her because when she's drunk she tends to get violent, sources said.
