In her younger years, Madonna tends to be unabashed in what she shares with the public. It seems the Material Girl has a limit as to what can be shared.

The Material Girl is asking her lawyers to prevent the organizers of an exhibition called "Simply Madonna: Materials of the Girl" from displaying the 17 racy love letters she wrote to her one-time paramour James Albright.

The letters aren't the only items on display though. There are costumes and other memorabilia as well. Check out ThisIsLondon to see some of the items.
