Marlene Dietrich, Property Mogul?

According to this article in the Guardian, Marlene Dietrich helped to raise funds for the development of a block of flats in Berlin's Tiergarten. The building was designed by Walter Gropius. When the Berlin Senate had problems finding funding for their proposed development, they put through a call to Dietrich, living in the US. The star apparently made some calls to Wall Street bankers and within two days, funding was secured.
