A studio executive was "way out of line" for scolding Lindsay Lohan for her absences from the set of her new movie, the teen actress' mother told "Access Hollywood" in an interview set to air Monday.

Last week, James G. Robinson, CEO of Morgan Creek Productions, chided Lohan in a letter for her behavior on a movie set and doubted her absence was related to heat exhaustion.

"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,'" Robinson wrote. "We are well aware that your ongoing all night heavy partying is the real reason for your so-called 'exhaustion.'"

Dina Lohan said the wording of the letter was "ridiculous."

"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," she said in an interview with Billy Bush. "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."

Lohan acknowledged that Lindsay has been late to the set on occasion and that the production once had to be scheduled around her to accommodate her lateness.

But she defended her daughter's most recent absence.

"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."

Lohan plays a troubled teen in "Georgia Rules," which also stars Jane Fonda and Felicity Huffman. Robinson said in the letter that Lohan has been frequently late for filming and has been "discourteous, irresponsible and unprofessional."

He said that if Lohan does not honor her commitments, the studio will pursue "full monetary damages."

Lohan, the star of "Freaky Friday" and "Herbie: Fully Loaded," was treated at hospitals twice in January ¡ª in London for a cut on her leg and in the Miami area for an asthma attack. In 2005, she was hospitalized for exhaustion and lost a noticeable amount of weight.

Lohan was back on the set of "Georgia Rule" without incident Thursday according to the trade publication "Hollywood Reporter."
