Dame Helen Mirren has been crowned Queen of Broadway as she won her first Tony Award for her role as the monarch in The Audience.
The star has already won an Oscar for her portrayal of the Queen in a film set in the aftermath of the death of Diana, Princess of Wales.
She resumed the role for a play which imagines the private weekly meetings between the Queen and Britain's prime ministers over her six-decade reign.
In the production, which has already had a successful run in the London, she morphs from a young princess to a modern day monarch.
Dame Helen beat fellow British actresses Carey Mulligan and Ruth Wilson, as well as Elisabeth Moss and Geneva Carr for the Tony for best performance by a leading actress in a play.
After her name was called by presenter Bradley Cooper she kissed her husband, director Taylor Hackford.
Arriving at the microphone on stage at Radio City Music Hall in New York, she proclaimed: "Your Majesty, you did it again."
She then dedicated her award to Hackford, saying: "What a massive, massive honour. Baby, this is for you and you know why."
Addressing the audience, she added: "It's nothing rude, incidentally."
She continued: "The foundation upon which I stand is beautifully built by an elegant and fleet play by Peter Morgan, an elegant and theatrical production by Stephen Daldry, an elegant and imaginative set by the great Bob Crowley, a stage management team who are certainly not elegant and a crew who are stupendous, a dresser who is a rock, producers who rock and of course an incredible cast of British and American actors who make the Atlantic look like a little creek you can just pop across.
"This is an unbelievable honour and I am so thrilled."
Richard McCabe, who plays Prime Minister Harold Wilson in The Audience, was awarded best performance by an actor in a featured role in a play and charmed the American crowd when he proclaimed "oh my giddy aunt" as he collected his gong.
He added: "Were he alive today, I know Harold Wilson would be very tickled."
The stage adaptation of hit novel The Curious Incident of the Dog in the Night-Time was named best play, beating Wolf Hall Parts One and Two, Hand To God and Disgraced.
Best performance by an actress in a featured role in a play was won by Annaleigh Ashford for You Can't Take It With You, while best performance by an actor and actress in a featured role in a musical was won by Christian Borle for Something Rotten! and Ruthie Ann Miles for The King and I respectively.
The Curious Incident of the Dog in the Night-Time continued its winning night when Alex Sharp was awarded best performance by an actor in a leading role in a play and Marianne Elliot won for best direction of a play.
The King and I was named best revival of a musical and David Hare's drama Skylight, starring British actors Carey Mulligan, Matthew Beard and Bill Nighy and directed by Stephen Daldry, won best revival of a play.
