Taylor Swift surprised just about everybody in the LA crowd last night.  Her ‘Speak Now’ tour was playing the Staples Center when she announced a special guest…..Justin Bieber.  And, the crowd went wild.

Thousands of happy girls screamed as the 17-year-old Canadian rock star took the stage to sing his hit “Baby” with Taylor.

Just as quickly as he appeared, Justin went away after the song and Taylor continued as if nothing had happened at all.  A pretty magical night in LA!
