Lady Gaga heel, Michael Jackson hat on auction in Paris

The February 11 sale at the Drouot auction house also features a leather ecritoire, or writing case, used by Marilyn Monroe and a pocket knife owned by Napoleon III, France’s last monarch and first president.

The Armani heel, lobbed by Lady Gaga in Paris during her second worldwide “Monster Ball” concert tour in 2009, is expected to fetch up to 9,000 euros ($12,000).

She threw the pair and then steadfastly stood on her heels for minutes at the end of the concert. But the auction only features the right shoe.

The Jackson fedora was crafted by Los Angeles firm Maddest Hatter which made only a number of limited hats for the King of Pop. He gave it to US singer Jonathan Davis at a 1984 concert in Buffalo.
