Mexico crowd boos Britney

Britney Spears has ended her world (mostly North America) tour by cutting short her final show in Mexico City. It added insult to injury after she made an obscene gesture upon arrival last week.

The 20-year-old pop princess sang four songs, then apologised, saying, "I'm sorry, Mexico. I love you. Bye," and left the stage.

Boos and jeers rained down when a public announcement asked fans to leave the stadium. Some concert-goers began throwing merchandise and chanting "fraud, fraud".

Spears was photographed extending her middle finger after she arrived at an airport in nearby Toluca. Spears later said the gesture was an angry response to paparazzi who she said nearly caused a wreck with her vehicle.
