Mash up artist  noticed that NSYNC’s 2002 hit single Girlfriend was a good match for Justin Bieber’s Boyfriend, which was ironically released just ten years later.

The resulting mash up is pop music perfection, mixing the sound from today with late 90’s popular NSYNC and Nelly like never thought possible. Who woulda thought the two Justin’s melded so well together?

The music video is featured on BuzzFeed, PerezHilton, and KLUC.
