Nicole Richie thinks she is the 'perfect' candidate to partner with Urban Decay because she is a mother.
The 36-year-old fashion designer was recently announced as the face of the beauty brand's new mascara titled Troublemaker, and the star thinks she is ideal for the ambassadorial role because she is a parent to Harlow, nine, and Sparrow, eight, - who she has with her husband Joel Madden - and she wants to prove make-up is not just for a select group of women.
Speaking to You magazine about her latest venture, she said: "Mums wear mascara and that alone makes me perfect for this collaboration."
The former 'Simple Life' star has long been a fan of the cosmetic giant, as she used to swear by their eyeshadows when she was younger.
She added: "I would buy a gunmetal-coloured eyeshadow called Uzi."
Urban Decay decided to join forces with Nicole because they wanted someone with "big eyes" and a "great personality" to front their campaign.
Wende Zomnir - who is the founder of Urban Decay - said: "We wanted someone with big eyes, a great personality and a bit of that troublemaking spirit. That's Nicole! She has a really unique sense of style. There are not a lot of A-listers who have that edge."
And Nicole's spouse agrees with Wende that Nicole is best suited for the role as he thinks she is the epitome of a "troublemaker".
Wende said: "The first time I met Nicole, her husband Joel said: 'Oh yeah, she's a troublemaker!'"
To which Nicole added: "Which also means breaking the rules of beauty. It's about self-expression; the idea that somebody else can't tell you what beauty is."
And Nicole insists her own fashion label House of Harlow prides itself on breaking style rules.
She added: "That's the principle behind House of Harlow.
"I would be like: 'That miniskirt is amazing and should be worn by somebody who's 5ft 9in.' Since then, I've made my own decisions about what looks good on me and how I feel confident."
