Australian actors including Russell Crowe, Hugh Jackman and Cate Blanchett also posted videos congratulating Kidman.

The award has previously gone to Julie Andrews, Denzel Washington, Robert De Niro, Martin Scorsese and Steven Spielberg.

Her husband Keith Urban, her children and her niece also attended the prestigious event.
