LATEST: The production company of Lindsay Lohan's film GEORGIA RULE have laughed off reports they have been further infuriated by the star's partying over the weekend (29-30JUL06), insisting "she's on her own time". Lohan landed in trouble with JAMES G ROBINSON, CEO of Morgan Creek Productions, last week (29JUL06) when she cancelled Wednesday's (26JUL06) filming because she was suffering from "exhaustion", despite the fact she had been partying at West Hollywood nightspot Guy's the night before (25JUL06). Robinson fired off an angry letter to "irresponsible and unprofessional" Lohan, fuming, "You have acted like a spoiled child and in doing so have alienated many of your co-workers and endangered the quality of the movie." However, on Friday (28JUL06), Lohan and her new boyfriend HARRY MORTON partied at Hollywood clubs Les Deux and Hyde, before flying to Las Vegas, Nevada to attend the BEACHER'S MADHOUSE show on Saturday (29JUL06). Morgan's Creek insist Lohan can party as much as she wants until she commences filming again tomorrow (02AUG06), when she will be expected to be on her best behaviour. GREG MIELCARZ, vice president of worldwide publicity, tells the New York Daily News, "We're off production now, so she's on her own time. "We're off until Wednesday. We're hoping she comes to work on time then."
