Nicole Richie's Sickies Send Her to the Hospital

Mother of two said to be "doing well" after checking herself into Cedars-Sinai for pneumonia

It may not be swine flu, but, whatever other nastiness is going around, Nicole Richie has it bad.

The starlet checked herself into the hospital with a major case of the sickies.

"Nicole has checked herself into Cedars-Sinai where she is being treated for pneumonia," her rep tells E! News in a statement. "She is doing well."

The 28-year-old mom of Sparrow and Harlow hasn't been at her best for quite some time now. Last week, she was too ill to attend her own bash feting the launch of her House of Harlow jewelry line at Bebe. By Sunday, she was clearly over spending time in bed.

"OK cold, it's been 6 days. Lets part ways graciously & keep it moving," she Twittered.

On Monday, her lawyer announced she wasn't feeling well right before she coughed her way through testimony against a pair of photographers.
