When Nicole Richie showed off a collection of funny family photos online last week, we couldn’t wait to get a closer look at what appeared to be new darker do. And this Saturday she finally revealed raven hair on the red carpet at the launch of her House of Harlow 1960 Holiday Collection at Bloomingdale’s in Costa Mesa, Calif. “Thanks to everyone who came out today in this terrible weather to hang out with me!” she Tweeted, adding, “OH! & P.S. I went brunette. I feel smarter already.” We don’t know about adding IQ points, but Nicole’s style quotient just keeps getting higher! Tell us: What do you think of Nicole’s new darker hair? Should she keep it or go back to blonde?
