Eccentric American chart-topper Lady Gaga is to sing for the Queen at this year's Royal Variety Performance.
The Poker Face star is the latest act confirmed for this year's show, producers said on Friday.
Lady Gaga, 23, is known for her dramatic stage performances, including sparking fireworks shooting from her bra and pretending to stab herself to death in a pool of fake blood.
She joins singers Bette Midler, Michael Buble, Miley Cyrus and comedian Whoopi Goldberg on the bill.
Urban dance troupe and Britain's Got Talent winners Diversity will also perform in front of the Queen and the Duke of Edinburgh as part of their prize for winning the TV talent show.
This year the Royal Variety Performance takes place at Blackpool's Opera House on December 7, the first time at the venue since 1955.
Comedian Peter Kay will host the royal event, which will be broadcast on UTV later in December.
The annual show is staged in aid of the Entertainment Artistes' Benevolent Fund, whose patron is the Queen.
