Wearing a hat perhaps inspired by the movie "Crocodile Dundee," Nicole Richie brought her family on a wildlife adventure in Australia on Tuesday. And, no, they weren't in the Outback. The "Fashion Star" mentor, her rocker-husband, Joel Madden, and their kiddos visited the Toronga Zoo in Sydney, where they got up close and personal with some of the furry residents. The family was accompanied by a handful of friends for their guided tour. They checked out giraffes, feeding one a carrot, and Richie, 30, played shutterbug, snapping photos throughout the excursion. For the special event, Harlow, 4, fittingly wore an owl T-shirt, while Sparrow, 2, had on a Baltimore Orioles cap — a nod to his father's favorite team. Meanwhile, Richie's NBC series "Fashion Star" wrapped up last night. She tweeted during the show — apparently from Australia — and when the ultimate decision was made to crown former teacher Kara Laricks the winner, she wrote: "Deciding on a winner was an emotional process for all. #exciting #heartbreaking #FashionStar." Although the show didn't generate big buzz in comparison to other reality competitions on the air recently, NBC announced that it will return for a second season next year. Richie also has another project on the horizon. It's been announced that she will design a limited edition collection for Macy's that will be part of their in-house Impulse brand, which will debut in stores and online in September. Of course, she also still has her jewelry line, House of Harlow 1960, and women's collection Winter Kate. She also recently launched an eponymous line for QVC.
