Nicole Richie says in a new interview that in some pictures she "definitely" looks too thin, but insists that when she looks in the mirror, "I think I look okay."
On an episode of The Tyra Banks Show she tells Banks,
"I definitely wouldn't mind gaining a few more pounds at all. I think that people's weight fluctuates. It happens. It happens to everybody." 
She also blames her thin appearance on stress
"A lot of people gain weight under stress and a lot of people lose weight under stress and I am one of those people that loses weight," she says – and her body type: "I am naturally a thin person and I am 5'1" and putting on five or 10 pounds, that looks like a lot on me." 
She says she is seeing a therapist weekly and recently hired a nutritionist to help her deal with stress and put on pounds.
"I just thought it was important to get the right team around me to make sure whatever I put in my body is helping me put on weight, and slowly but surely, I am doing so."
