Nicole Richie’s shockingly frail frame has friends concerned for her health once again after she’s appeared looking like skin and bones lately.

The 31-year-old Fashion Star mentor wore a strapless red dress to the Valentino Fashion show in Paris on March 5, and a new report in Star magazine says her friends are fearful that she’s getting too thin.

Nicole sought treatment for anorexia in 2006, and according to Star, there are concerns that she may have relapsed.
