Nicole Richie Celebrates 31 Years of Great Style (Gallery)
Nicole Richie -- who turns 31 today -- has come a long way since her Simple Life days.
The mother of two has successfully parlayed a reality TV role into a successful career as a fashion designer -- and icon.
The former party girl successfully parlayed her enviable personal style into a successful clothing and accessories line called House of Harlow, after her daughter. The momtrepreneur just launched a new collection for QVC too, and wore four different outfits (in one day, no less!) to promote it.
But the Fashion Star judge wasn't always a style star...
It wasn't too long ago that Richie and Paris Hilton were attached at the hip, and the birthday girl was sporting some questionable get-ups while filming The Simple Life.
But after leaving her hard-partying ways and sidekick status behind, Richie embraced a more sophisticated style.
Proving she could put together an outfit, Richie started landing on all the best-dressed lists, and suddenly everyone wanted her modern take on hippie chic.
Even though she's now made her style available to everyone, Richie continues to earn styling nods for her unique spin on bohemian glamour.
So in honor of her 31st birthday, check out Richie's style transformation over the years.
