Nicole Richie and Joel Madden arrived home in LA yesterday after a flight from Australia, but they didn't waste much time before reconnecting with some of their friends. Nicole joined Joel for lunch with their pals at the restaurant Sugarfish. The Richie-Maddens had been Down Under with kids Harlow and Sparrow so that Joel could record the debut season of the country's version of The Voice. It seems they all grew to be quite fond of Australia, and Joel even tweeted that he'll miss being there. He's ready to dive back into life in California, though, and also wrote on Twitter, "It's been a few months since i've been home in America. I feel out of the loop, what have i missed?"
