Justin Bieber has shaved his moustache

The Canadian singer, whose appearance has changed dramatically since he first arrived on the pop scene, can be heard asking a friend, "Should I do it?" and "RIP 'stache!"

Justin, 20, begins the video by applying shaving cream to his face and asking his friend, "Is this how you do it?", who responds by saying: "I think that's how you do it."

The pop star then says: "Here I go!" as he takes his battery-powered razor and begins to remove the fluffy hair.

And though the before and after difference was negligible, it succeeded in returning Bieber to the clean-cut image that saw him become a huge star around the world, when he released 'Baby' in 2010.

The singer posted a shot of his newly-shaven face on his Instagram page, with the video appearing to show Bieber and his friend at the 16,000 square foot mansion he's been renting in the Hollywood Hills.
