Rebecca Black Yanks 'Friday' Off YouTube

Rebecca Black has officially pulled her "Friday" video off of YouTube.

A rep for Black tells, "We can confirm that we submitted a Take Down Notice to YouTube as a result of the dispute we have with Ark Music regarding the 'Friday' video."

Black's people have threatened legal action against Ark -- claiming the company that produced and wrote the song is wrongfully exploiting her image and her song because Ark does not own the rights to either.

Earlier this week, Ark -- which ran the YouTube account that hosted the video -- set up "Friday" as a $2.99 YouTube video rental. Clearly, the move pissed off Black's camp ... a camp that was simply looking forward to the weekend.
