Nicole Richie admits she's no "fashion icon" as far as her family is concerned.

The Winter Kate designer may be a mentor on American show Fashion Star, but says when she's at home, she is anything but.

"I'll tell you right now that no one's calling me a fashion icon. Now that you mentioned it, I'm going to start requesting that Joel start calling me that once every day, at least."

The 30-year-old former party girl - who is also the brain behind accessories line House of Harlow - has now branched out into fragrances with her new scent set to hit the stores in autumn.

"I knew exactly what I wanted to do because my mum would wear a combination of a few different oils and a few different lotions. It's a smell that's very special to me and reminds me of my mum," she told USA Today, explaining her perfume choice.

But despite her success, the Hollywood entrepreneur has vowed not to take it for granted and lose her edge.

"It's important to me to not stay focused on how people feel about my work. The second when you feel you've reached a certain point and you feel you don't need to work anymore, that's when you're in danger. My mind doesn't work, 'Oh, I've gotten respect, I'm good now.' I don't think that way at all. I work all season, year round. As long as I'm doing that, I'm doing my job. You're only as good as your last collection."
