Rebecca Black Joins Katy Perry On Stage At L.A. Concert
Katy Perry thrilled fans at a concert in Los Angeles on Friday by inviting internet sensation Rebecca Black on stage.
The pop star took her California Dreams tour to the Nokia Theater, playing through her hits and covering tracks by Whitney Houston and Jay-Z for a sold-out crowd of more than 7,000.
However, the most surprising moment of the night came when Perry began belting out Black's hit Friday, before bringing the 14 year old out to join her for the chorus.
Black shot to fame earlier this year when the promo for Friday scored millions of hits on YouTube.com, before going on to star as a popular student in Perry's video for Last Friday Night (T.G.I.F.).
