If you’re asking who the heck is Rebecca Black…you certainly don’t watch TV enough (good for you). There was no news magazine show that did not feature her viral music video on YouTube in the last two months. She’s the 13 year old girl who was singin’ about “partyin’, partyin” over the weekend. Cheesiness sells perhaps. Internet sensation, Rebecca Black whose amateur music video centered on her favorite day of the week and her love for “partyin’” gets the rare chance to work with Katy Perry. To have someone as powerful as Perry expressing her support for you, we’re hoping Black would learn a thing or two in making better videos…and singing better. Black has a cameo appearance in Perry’s latest music video, “Last Friday Night” and it will be released on the 14th of June.
