The FUN, FUN, FUN is over ... Rebecca Black has officially pulled her "Friday" video off of YouTube ... and TMZ has learned it's all over a fight over Rebecca's image.
TMZ spoke with a rep for Black who tells us, "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."
As we previously reported, 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.
