Rebecca Black
Rebecca Black (born June 21, 1997) is an American pop singer and dancer who gained extensive media attention with the 2011 single "Friday". Her mother paid $4,000 to have the single and an accompanying music video put out as a vanity label through the record label ARK Music Factory. The song was co-written and produced by Clarence Jey and Patrice Wilson of Ark Music Factory. After the video went viral on YouTube and other social media sites, "Friday" was derided by many music critics and viewers, who dubbed it "the worst song ever." The music video received around 167 million views, causing Black to gain international attention as a "viral star", before being removed from the site on June 16. Black re-uploaded it in her own channel three months later.
