Richie To Undergo Treatment

Nicole Richie has checked herself into a private facility for an undisclosed treatment. According to a statement from Richie's reps, published on E! News, "She is working with a team of doctors and specialists whose focus is nutrition..."

Nicole will undergo diagnostic treatments to determine why she can't gain weight. Recent photographs of Richie have created a buzz in Hollywood that she may have issues with food.

Nicole's reps say "this is not a treatment for an eating disorder." The reps add that Nicole wants to deal with her weight issues in the healthiest possible way.

Production on the current season of "The Simple Life" will be put on hold indefinitely.
