Lohan's publicist Leslie Sloane Zelnick told MTV that Lohan had been diagnosed with bronchial asthma as a child but has not had an attack in several years.
"It's the first attack since I've known her," Zelnick said. "She's had attacks before, but not that many, and not recently. She's taking it easy now, she's resting comfortably. She's just tired and not feeling too good. It took a lot out of her."
Zelnick told MTV that Lohan is expected to remain in the hospital for a few days, according to their report on Tuesday.
Lohan is set to begin filming her next film "Chapter 27" in two weeks. That film is based on Mark David Chapman, the man that murdered John Lennon outside of his New York apartment building in 1980. Jared Leto will play Chapman and Lohan is to play a Lennon fan that befriends Chapman a few day's before he carried out the murder of the music legend.
