Everyone knows that Justin Bieber has the best head of hair around -- but when push comes to shove, he just doesn't have the scruff.

The pop star was spotted out in London sporting a drawn-on moustache. After dinner, the Biebs and his Sharpie-drawn accessory headed out with a remote controlled helicopter to cause a little mayhem with his bodyguards. Bieber hit the town with his faux-'stache just days after he received a Grammy nomination for Best New Artist.

For whatever reason, Justin's look often grabs as much attention as his tunes and always leaves us wondering what's next for the young pop star.
