Gaga ditched a huge ruffled plastic collar when greeting her Majesty after her performance, which had the “Speechless” singer — and her piano — suspended 12-feet in the air, her long dress hanging all the way down to the stage.

Also on hand for the event, which raises money for the Queen’s Entertainment Artistes’ Benevolent Fund, were Bette Midler, Michael Buble, and Miley Cyrus, who wore the most rique outfit of the night — super short hotpants.
