Katy Perry- Last friday night (T.G.I.F)

In this brilliant new video from pop superstar and style icon, Katy Perry, we see her alter ego 'Kathy Beth Terry' throw a wild party and given a make-over by Rebacca Black. However this video is a message from Katy perry to show that girls with braces are beautiful and as one of her friends say in the music video...'i don't care what anyone says about you, your cool!' The music video guest stars Glee's Kevin Mchale and Rebecca black. this video makes you wish you never made fun of anyone,entertaining and fun filled.
