Lohan blasted by 'Georgia Rule' boss

Lindsay Lohan has been sent a strongly-worded letter by the boss of the production company funding her latest film Georgia Rule.

Apparently the actress has been late arriving on set on several occasions since filming started, and recently missed a whole day blaming overheating and exhaustion.

However, Morgan Creek Productions CEO James G. Robinson has blasted the young star's behaviour, labelling it "discourteous, irresponsible and unprofessional".

His letter to Lohan, a copy of which has found its way on to The Smoking Gun, also makes it clear that the movie's producers are unimpressed with the 20-year-old's excuses.

"We are well aware that your ongoing all night heavy partying is the real reason for your so called 'exhaustion'. We refuse to accept bogus excuses for your behaviour," Robinson stated.

The executive also warned: "If you do not honor your production commitments, including your scheduled call time for tomorrow, and any call times thereafter, we will hold you personally accountable."
