Let's be honest: Oprah Winfrey is one rich lady. So she can obviously afford to cough up some dough in the name of charity. But, as always, Lady O has gone above and beyond this year. In fact, she was named the most charitable celebrity for donating more than $40 million! Plus, for her last season of The Oprah Winfrey Show, the hostess with the mostest treated her entire audience from the season premiere to an Australian vacation. Now that's being a good mate!
