Lindsay Lohan had a health scare on Sunday night that was bad enough to send the 26-year-old actress to the hospital for treatment, but her rep tells CNN that the "Liz & Dick" star is on the mend.

It was asthma, Lohan's rep said, that landed the star in a New York City hospital. "Lindsay was treated and released, and is doing fine," the rep said. (According to her mother, Dina, the actress has been treated for "bronchial asthma ever since she was little," as she told The New York Daily News.)

LiLo started to feel sick over the weekend, but she didn't let it interrupt her party plans. She told The New York Post that she was recovering from pneumonia, but didn't want to miss DJ Steve Angello perform at Central Park.

"I have been really sick with pneumonia but I have been working," Lohan told the paper. "I have been shooting 'Scary Movie' with Charlie Sheen. He was really great to work with and gave me some good advice about surviving in this business."
