Reality TV socialite Nicole Richie has revealed that she’ll be launching her own jewelry brand.

The 26-year-old first-time mum has teamed up with Mouawad, the same name behind supermodel Heidi Klum’s jewelry line, to design a collection of mix ‘n’ match costume jewelry.

“It’s all costume jewelry. I like to play with jewelry and mix and match. I’m working with this really talented woman named Shelley Gibbs. She’s an artist and she sketches everything,” Richie told People Magazine.

“Everyone’s been really mellow and able to work around my schedule. If I need to go feed the baby, I do it.”

Talking about her newborn daughter Harlow Winter with boyfriend Joel Madden, Richie said, “She gives life a whole new meaning and a whole new purpose.”

Nicole is also an author, actress and singer, who’s also launching a children’s clothing line and insiders say a signature perfume is also in the works.
