Lily, meanwhile, was also stunning in a glittering batwing dress, accompanied by a sleek fringed updo.
Held in the palatial Villa Erba, the special gala saw guests enjoying Martini sparkling wines and a collection of cocktails made with Martini vermouth and created by some of the world's top bartenders.
Entertainment was provided by the lovely Lily as well as Chilly Gonzales, who performed on a special floating stage.
Mark Ronson also filled the dance floor with a specially created set and renowned Orchestra Italiana Del Cinema entertained guests with a selection of Fellini film scores.
Sounds awful, right?
