Preggers Nicole Richie is closer than ever to figuring out what she'll wear for her shotgun wedding to rocker Joel Madden. 24Sizzler.com reports that Nicole is considering "Giorgio Armani, YSL, maybe Zac Posen, and some L.A. designers she likes. Nicole's not fixated on getting some huge designer name, though, like how Katie [Holmes] got Armani. And she's already checking out L.A. bridal shops. She's reached out to high-end L.A. bridal boutique Renee Strauss for help in getting a wedding dress fast, so she's fueling the wedding fire, but she loves it. Let's hope she finds something in an empire waist style.
