Nicole Richie [photos] has been admitted to a Los Angeles hospital and is being treated for pneumonia.
"Nicole has checked herself into Cedars-Sinai where she is being treated for pneumonia," says her publicist. "She is doing well."
The 28-year-old mom had been complaining of feeling less than her best for days.
Last week, she was too ill to attend the launch of her own House of Harlow jewelry line at Bebe.
"Ok cold, it's been 6 days. Lets part ways graciously & keep it moving," she said on Sunday via Twitter as she was still trying to get over it.
Then the following day, at a court hearing to get restraining orders against two paparazzi, after she appeared rather subdued, her lawyer had to inform the judge that she wasn't feeling well.
In fact, the appearance spawned rumors, which her publicist had to shoot down, that she was suffering from the swine flu.
Richie gave birth to her second child, a son, Sparrow James Midnight Madden, in September.
