Katy Perry brings Rebecca Black on stage for a duet
Katy Perry wowed crowds in Los Angeles over the weekend with three dates there, but the real surprise came when she brought out a special guest for a duet.
Quieting the crowd, the 'Teenage Dream' hitmaker beckoned out a demurely dressed Rebecca Black for a rendition of her viral hit 'Friday'.
26-year-old Perry has been covering the track as part of her set during the California Dreams tour and treated her L.A audience to a live acoustic duet with the original singer herself.
Black also features in the music video for 'Last Friday Night (T.G.I.F.)' and you can watch her appearance during Perry's show at the Nokia Theatre on August 5 here:
