Pregnant Nicole Richie at the Richie-Madden Children's Foundation eventWe can't say we're shocked by this news. Nicole Richie is a fashion maven through and through. Every time she steps out -- whether she's going for coffee or hitting the red carpet -- she's impeccably dressed. So when she brought that same amazing sense of style to her jewelry line, House of Harlow, fashionistas around the world took note and snatched it up. The line sold out in the pre-order!

House of Harlow hasn't even hit stores yet. This line, done by Nicole and co-designed with Pascal Mouawad, is going to be a sensation.
