Photos of Nicole Richie, Joel and Harlow Madden Eating Dinner With Takashi Murakami in LA

Nicole Richie returned to the states over the weekend and quickly jumped back into her casual attire for dinner Sunday night with Joel and Harlow in LA. While Nicole was away Joel and Harlow kept each other company, but the trio looked happy to be reunited after her weeklong trip to Europe with Sparrow. Nicole didn't let any of the fun moments on her trip go undocumented sharing the highlights in an extensive album of pictures with fans, friends, and sights. During dinner Joel ran into legendary Japanese artist Takashi Murakami — of Louis Vuitton fame — tweeting a photo as he swapped digits with him. Nicole had her own exciting celebrity moment yesterday when she spotted Rihanna wearing House of Harlow 1960 bangles while giving a televised interview in England.
