Long before Justin Bieber tapped Big Sean to rap on his song, "As Long As You Love Me," the Backstreet Boys recorded their own song with the same name. It was 1997 - and Justin Bieber was only 3 years old.

Web sensations Michael Henry and Justin Robinett have put together a medley of Bieber's "As Long As You Love Me" and BSB's pre-Millenium version - perhaps inspired by the mash-up of *NSYNC's "Girlfriend" and Bieber's "Boyfriend" that went viral last month.

Check out the mash-up of Justin Bieber's new song with the Backstreet Boys' 1997 track of the same name:
