Nicole Richie is home from the hospital after battling pneumonia.
"So I stepped off the plane after a month out of the country, and basically went straight to the hospital for the week," her beau Joel Madden posted on his band Good Charlotte's website Friday.
Added Madden, "But don't worry all is well and we are home with no problems."
Richie posted on Twitter Sunday, "Ok cold, it's been 6 days. Lets part ways graciously & keep it moving."
On Wednesday, a rep for Richie told "Extra": "Nicole has checked into Cedars-Sinai, where she is being treated for pneumonia. She is doing well."
The mother of two was too sick to attend the Nov. 10 launch of her House of Harlow jewelry line at Bebe in Los Angeles.
