Actress treated during Los Angeles heat wave

Is Firecrotch "Hot" or "Not"? Well, now we know the answer.

The sometimes redhead had to seek treatment Wednesday, July 26 at a Los Angeles area hospital after being overcome by heat while shooting her latest film "Georgia Rule," report news sources.

Publicist Leslie Sloane-Zelnick confirms that her client was filming in 105-degree weather for 12 hours when she began to suffer. After being transported to the hospital, she underwent treatment for overheating and dehydration and given a vitamin B-12 shot.

The 20-year-old is reportedly well enough to report back to work, which shouldn't be a surprise since People reports she was seen partying at a nightclub later that evening.

In the Garry Marshall-directed dark comedy "Georgia Rule," Lohan plays the rebellious stepdaughter of a model citizen (Cary Elwes) who's molesting her. Her mother (Felicity Huffman) then sends her to spend the summer with her grandmother (Jane Fonda).

Lohan, known for her Disney remakes of "The Parent Trap," "Freaky Friday" and "Herbie: Reloaded," was recently seen in "Just My Luck" and Robert Altman's "A Prairie Home Companion." Her other upcoming projects include "Bobby" and "Chapter 27."

She's also the recent victim of a hacker/jokester who's been emailing people in her BlackBerry address book and pretending to be her. Lohan suspects former party gal pal Paris Hilton, a former hacking victim herself, who called the accusations "silly."
