Madonna secretly flew to Chicago last week to attend the recording of the "Surprise Oprah - A Farewell Spectacular" show, which was then broadcasted on TV May 24-25.

As a tribute to Oprah Winfrey, Madonna made a very touching speech and explained how she has acted as a role model and source of inspiration for millions of women around the world.
