A new video has been going around youtube, a video mash-up between Justin Bieber’s ‘Boyfriend‘ and NSYNC’s ‘Girlfriend‘.

It amazing how well these two songs have been matched up, if you didn’t know it was mashed up you would even think it was really one and the same song. Since the feel of both songs is also the same.

So if you are a really big Justin Bieber and Justin Timberlake fan then this is your lucky day!

Take a look at the video mash-up:
