Pink takes over Trafalgar Square
Pink thrilled thousands of volunteers filming a commercial in London this week when she made a surprise visit to sing for the crowd.
More than 13,000 members of the public converged in the British capital's Trafalgar Square to participate in a mass singalong for phone company T-Mobile's new TV ad.
Those gathered were instructed to sing hits such as The Beatles' 'Hey Jude' and Britney Spears' '...Baby One More Time', while the event was filmed by 24 cameras and recorded by more than 2,000 microphones.
The crowd was stunned when an image of singer Pink was transmitted onto giant screens hanging over the square.
And they were then sent into a frenzy when cameras panned around to reveal the singer was at the event in person.
The star joined in halfway through a rendition of the Erma Franklin track 'Piece of my Heart', before removing her hood and singing her hit song 'So What?' on a raised platform.
Speaking after the event, she told reporters: "What a fantastic experience! Everyone singing along together in the middle of London - it was incredible. I was thrilled to be a part of such an amazing event and to share it with so many people."
