Queen Elizabeth II mingles with the stars.

The monarch chatted with some of the biggest names in the music business after a jubilee concert held in her honor.

Australia's Kylie Minogue escorted the Queen down the line of stars.

Her Majesty then met Paul McCartney, Anne Lenox and Stevie Wonder who topped the bill at the star-studded Diamond Jubilee celebration.

The monarch missed the first half of the concert.

She was visiting her husband, Prince Philip in hospital where he's being treated for a bladder infection.

Elton John took a moment to express concern for the Prince.

But the show must go on...for the tens of thousands of fans who lined the streets of London, and of course, for Her Majesty herself.
