British actor Helen Mirren has been honoured as woman of the year by Harvard University's Hasty Pudding Theatricals, twerking as part of the traditional spoof roast.
Mirren at first tried to sign the word "twerk," then let slip a curse word and danced.
She said she had tried twerking privately in her bedroom, but having to do it in public was humiliating.
She also joked that being honoured by Prince Charles as Dame of the British Empire at Buckingham Palace didn't come anywhere close to getting the ceremonial Hasty Pudding pot at Harvard. The festivities also included a parade.
Mirren, 68, won the 2007 best actress Oscar for her role as Queen Elizabeth II in The Queen and has been nominated on three other occasions.
She also appeared in Age of Consent, Gosford Park and The Madness of King George.
She said she would still like to play the powerful 18th-century Russian monarch, Catherine the Great.

It annually honours performers who have made a lasting and impressive contribution to entertainment.Emmy Award-winning actor Neil Patrick Harris will be honoured as man of the year on February 7.
The winners of 2013 were Marion Cotillard and Kiefer Sutherland.
