Taylor Swift shocked by album sales

The American singer was speaking at Westfield London shopping mall on Tuesday, where she was switching on the Christmas lights.

Speaking after the big moment, Taylor said: "I had hoped that my fans would get what I was doing there - that they would embrace it.

"And the fact that they celebrated that and more than 1 million of them went out and bought it the first week and it became my first UK No 1 album, it is absolutely unbelievable."

The Grammy-winner rewarded her British fans at the event by performing songs for the album.
