　　U.S. music superstar Madonna tries to silence the press as she holds up a copy of her newest children's book entitled "Lotsa De Casha" at a reading and book signing event in New York June 7, 2005.

　　Take it from Madonna, the self proclaimed "Material Girl," money can't buy happiness.

　　That’s quite a lesson from the 46-year-old pop diva, whose fifth children's book in the past 18 months "Lotsa de Casha," hit store shelves this week.

　　"Lotsa was by far the richest man in the country. He had everything that money could buy," is the opening line of her latest book. "But there was a teeny, tiny problem. No matter how much money Lotsa de Casha made, he wasn't happy."

　　The short book concludes with the moral, "When you learn to share, you will not only find happiness. You will also find a friend."
