Nicole Richie and Diane Kruger Pictures at UNICEF Ball

Nicole Richie and Diane Kruger both went with black, but mixed it up with sheer panels and hot cutouts at the 2011 UNICEF ball at the Beverly Wilshire last night in LA. This weekend is a big one for Nicole, since she and Joel Madden will be celebrating their first wedding anniversary — check out Nicole's and Joel's cutest pictures through the years. Brooklyn Decker was sporting a glow, fresh from her Bahamas vacation with husband Andy Roddick last weekend. The model-turned-actress is also looking gorgeous in the first trailer for What to Expect When You're Expecting. Diane Kruger had her own tropical vacation recently: she spent Thanksgiving lounging in retro bikinis alongside hot boyfriend Joshua Jackson.
