Nicole trying to find out why she can't gain weight

Nicole Richie has officially announced that she is getting treatment for her inability to gain weight. "Nicole Richie has decided to undergo diagnostic treatment to determine why she's not been putting on any weight," her rep said in a statement. "She is working with a team of doctors and specialists whose focus is nutrition. It is important to Nicole that she achieves this goal in a healthy way as this is not a treatment for an eating disorder." A source close to the Simple Life star said, "She's tired of everyone saying, 'You don't eat,' because she does. She wants to gain weight. It wasn't anyone saying, 'You have to go do this' - it wasn't an intervention. It was her saying, 'I'm tired of people saying this about me, I'm going to get some tests.' It was a personal decision."
