Katy Perry's "Last Friday Night (T.G.I.F.) made it to No. 1 on the Billboard Hot 100, making her the first female artist in chart history to score five No. 1 hits off the same album.
I love me some Katy Perry and it looks like her new song will be meshed with some serious video goodness!!! I can't wait! Why do they have to tease me so?!?!?!?
