Over the past decade, Nicole Richie has gone from a brash reality star to full-fledged fashion designer and actress. However, her transition from The Simple Life to style icon included a drastic weight loss transformation that had many fans concerned.

While starring on her first reality show alongside BFF Paris Hilton, Nicole was your typical girl-next-door. However, having to stand next to the glamazon that is Paris, it doesn’t surprise us that Nicole may have gotten insecure about her weight and changed up her diet and exercise routine for the cameras.

At one point, it was reported that Nicole had dropped down to 88 pounds — and photos of her on the beach in 2006 really had fans convinced she suffered from an eating disorder. Nicole responded to the rumors and agreed that she was struggling with her health.

“I know I’m too thin right now, so I wouldn’t want any young girl looking at me and saying, ‘That’s what I want to look like,’ ” she told Vanity Fair at the time. “I do know that they will, which is another reason I really do need to do something about it. I’m not happy with the way I look right now.”

She added that she had turned to a nutritionist to help her put back on some weight, and today, she is looking better than ever. However, Nicole, who is set to star in the upcoming NBC comedy Great News, doesn’t regret her past.

“It is no secret that I have, at times, taken advantage of my time on this planet. And as much as I have to look at those moments and learn from them, as we all do, it’s important for me to have gratitude for that time, too. Not shame. Being ashamed of your life is not OK,” she wrote for Lenny Letter. “I realized I am actually extremely thankful I was so beastly in front of the world for a few reasons. It’s so bad in people’s minds that there’s nothing that can embarrass me now.”

The mother-of-two continued, “So as a mom at a school, as an actor on a comedy series, as a designer at Fashion Week, I don’t have to worry that I won’t fit into expectations, but rather, my inner acceptance and peace will allow my true self to shine through and carry me along.”
