The mother of teen queen Lindsay Lohan has hit back at the studio head who reprimanded the actress for her tardy behaviour via a letter and email.

James G Robinson, the chief executive of Morgan Creek productions sent the letter to Lohan following her stint in hospital due to �exhaustion� and after she failed to show up on set of her new film �Georgia Rule�.

Robinson�s letter � which was posted on the SmokingGun website � read: �You and your representatives have told us that your various late arrivals and absences from the set have been the result of illness; today we were told it was 'heat exhaustion'.
We are well aware that your ongoing all night heavy partying is the real reason for your so-called 'exhaustion�.�

Calling Lohan, "discourteous, irresponsible and unprofessional,� he continued, �You have acted like a spoiled child and in so doing have alienated many of your co-workers and endangered the quality of this picture.�

Dina Lohan has claimed that Robinson was �way out of line� for telling her daughter off for her behaviour�something maybe her mother should be doing?

She said to Access Hollywood: �Maybe he has personal issues with whomever and it came out with my child,

�I don't think it was a smart thing to do to a young girl,�

�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 she can't breathe.�

She did however admit that her daughter had been late for filming on a number of occasions.

Robinson has defended his actions saying that was �just trying to get the movie made,�

�I did what I felt I needed to do on behalf of the movie and on behalf of her, too. I wanted to set some limits.�

Well, somebody has to�
