Wow! Who saw this coming? Justin Bieber has just released his second official single from his Believe album and it shows him in a decidedly more adult light. As Long As You Love Me is a dance track that features some excellent even-for-Bieber dance moves and an appearance from Big Sean. The video features some acting from Bieber along with – what?! – Michael Madsen, that film fans will know from movies like Reservoir Dogs.

Madsen plays the father of the girl Bieber is in love with and warns him to stay away from her – or else! Warning to those that may not want to see their precious Bieber in a scuffle: he does get a little bloodied and bruised, as you can see in the picture above.

Check out the video after the cut (if you dare!) and tell us if you like what you see. Is the song better than Boyfriend? Think it will top the charts? Let us know your thoughts!
