George Clooney headed out to Sydney's Star City Casino yesterday afternoon. He arrived Down Under Sunday in order to speak during a leadership conference alongside Martha Stewart, Russell Simmons, and microlending pioneer Muhammad Yunus, and the actor's expected to leave the country today. Admirers could pay $1,000 to lunch with George Clooney yesterday and hear him speak about his work to bring attention to political crises in Africa. The trip to Australia netted George $600,000, and he reportedly donated the fee to charity. His girlfriend, Stacy Keibler, meanwhile, stayed behind in LA and was seen checking out a Jay-Z and Kanye West show. Stacy tweeted that she's a big fan of Kanye's song "Runaway" in particular, since she empathizes with his lyrics about toasting haters.
