Rebecca Black Thanks Justin Bieber For Singing ‘Friday’

Justin Bieber sang a bit of ‘Friday’ by Rebecca Black during his concert at Capital FM Arena in Nottingham, England on Thursday (March 24). The move prompted 13-year-old Black to tell her Twitter followers (@MsRebeccaBlack) moments ago:

OHOHOH. I thanks to @justinbieber for singing a little piece of Friday at your concert. #thatwasepic (:
