Nicole Richie ''live and breathes'' designing.

The 35-year-old fashion designer - who debuted her jewellery line House of Harlow 1960 in 2008 and has since expanded the brand to include a clothing range - has admitted creating showstopping clothes and accessories for her label is something she enjoys spending all of her time doing.

Speaking about her involvement with creative process for the fashion house, the golden haired beauty - who is the adopted daughter of 'Hello' hitmaker Lionel Richie - said: ''I live and breathe it. I wouldn't spend my time doing this if I couldn't 100 percent be there.''

And the former 'The Simple Life' star has revealed Los Angeles has been a ''huge inspiration'' for her and had a large influence on her pieces.

She explained: ''LA was a huge inspiration for me.''

Although Nicole didn't attend a Fashion School to learn about designing, she believes after spending a ''long enough'' in the industry you begin to learn the ropes.

She said: ''[This business] is something I've had to just learn. It's like throwing a baby in a pool. I love learning.

''I never turn my nose up at an opportunity where I'm able to be around someone who's had more experience than me. Everybody knows what they're good at, and everybody is assigned a certain task. I definitely stay in my lane. But if you stay in the business long enough, you figure it out.

''Now is such an interesting time because there are so many changes in how we communicate with each other.''

And the star has advised budding creators to be ''authentic''.

She told Prestige Online: ''Be authentic to yourself, and surround yourself with people who have been in the business longer than you. Take every opportunity to just learn, to always keep your ear open and learn about every aspect of the business. But what's more important is to tell your story in an authentic way, and get it out there.''
