Although Nicole Richie first came into the public eye as Paris Hilton's sidekick on the reality TV show, The Simple Life, she has since made a name for herself as a fashion and accessories designer and vintage lover. On Saturday, the mother of two was in the Hamptons, celebrating a collaboration between her brand, House of Harlow 1960, and e-commerce destination Revolve. "I’m from L.A. and so is Revolve," she noted, explaining that the collection celebrates "a city that I love, the color palettes, the space and the air, and that overall Los Angeles feeling."

But it was Richie's former expertise, television, that was the most surprising topic of conversation. A few days earlier, Tina Fey cast the designer in her new sitcom Great News. Here, Nicole Richie opens up about her personal style, and how she feels about taking on a new challenge..

Favorite store in L.A.: To be honest, I do a lot of shopping online, I just don’t have time. I feel like when I go to thrift stores and vintage stores and that type of thing, you really have to be there for that, you have to do it in person, but I’ve been doing a lot of online shopping.
