Leonardo DiCaprio sure knows how to get his way, reports New York magazine, which says that at a birthday party for independent producer Mary Fanaro in Malibu last week the “Titanic” star wanted to leave. But when his friends refused to move on with him, Leo starting flicking the lights on and off, “to signal the party’s end,” says New York, “despite the fact that Barry Diller, Elisabeth Shue, Toby Maguire and Kevin Costner were still enjoying themselves.” Even when a young woman asked him to stop and placed her hand over the light switch, Leo continued. He finally stopped, says the magazine, when he became more interested in actress Kate Hudson than in annoying the others.
