I know some people have been commenting and the Prince’s Palace of Monaco on their Facebook page have released a statement so some of you can shut up: 

The Princely couple, invited by M.Robert A. Iger, Chairman and Chief Executive Officer of the Walt Disney Company, will attend to the Oscars this evening in Los Angeles.
The Prince Albert II of Monaco Foundation and Disneynature signed a global agreement in 2010 to help raise public awareness through films and documentaries on the emergency to protect the environment.

Plus, the Monegasque Princely Family, have a connection to Hollywood.
