I already told you that Lindsay Lohan didn’t collapse just because she suffered from overheating and exhaustion on the set of her latest movie “Georgia Rule” and it seems that James G. Robinson, who’s producing the movie, also doesn’t believe her. A harsh letter from the production company Morgan Creek, obtained by The Smoking Gun, was hand-delivered to Lohan’s residence at the Chateau Marmont.

To date, your actions on Georgia Rule have been discourteous, irresponsible and unprofessional. You have acted like a spoiled child and in doing so have alienated many of your co-workers and endangered the quality of this picture. Moreover, your actions have resulted in hundreds of thousands of dollars in damage. We will not tolerate these actions any further.

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….I urge you to take this letter seriously and conduct yourself professionally.

Well, next time I’m sure they’ll think twice before hiring that spoiled little brat.

Update! Lohan’s mother, Dina, spoke exclusively to Access Hollywood’s Billy Bush about the letter her daughter received from the studio. She told Bush, “The wording was ridiculous.” When asked if she thought the executive, James G. Robinson, was out of line and what brought on the unprecedented blast, Dina said, “I feel when you are 19 (years old) it is way out of line… Maybe he has personal issues with whomever and it came out with my child. I don’t know him. I can’t judge him. I don’t think it was a smart thing to do to a young girl.” When asked if there was any truth to claims in the letter, Dina came to her daughter’s defense saying, “Lindsay was in 105 (degree weather) saying, ‘Mommy, I feel sick; like I am going to faint.’ She took herself to the hospital. She has asthma and in extreme cold or heat you can’t breathe.” Dina added, “…I’m a mother and will do what I need to do to protect my child…I don’t feel it should be aired out and everyone should know. It’s personal.”

The night before her daughter collapsed on the set, her mom was spotted partying with two gal pals into the wee hours at an Amagansett nightspot so I’m not sure she’s a good example to follow. Like mother, like daughter.
