It seems the girls have "Bieber Fever"!! Watch as they  show us how to do a Carly Rae Jepsen and Justin Bieber concert right! 

I'm taking notes....and to be honest I don't think I could handle all the screaming.  I mean, even I tend to annoy myself with my high pitched I love you Bieber wails sometimes...hahahah!  I kid, I kid!
