LINDAY MAKES A QUICK GETAWAY!

LINDSAY LOHAN - once warned publicly by movie bosses to stop her non-stop partying or get fired/sued - freaked when an assistant producer on her new flick "I Know Who Killed Me" suddenly showed up in the wee hours at a Hollywood Hills booze-and-boogie bash she was attending! Due on set in just hours, Lindsay - fresh out of rehab and terrified the guy would tattle if he spotted her - quickly grabbed her purse and exited via a window in the john!
