We're not sure about Justin Bieber's new accessory. Nice bum though.

Justin Bieber performed at Wango Tango in America yesterday, along with Nicki Minaj, Maroon 5, Pitbull, Carly Rae Jepsen and loads more.

We're sure his performance was great and it was a great day blah blah blah, but what we're unsure of is that weird, fluffy contraption that he has hanging from his trousers.

We know he's cool and all that, and that girls tend to cry/pass out/wet themselves when they see him, but even he can't pull this off.

And more to the point - WHAT EVEN IS IT?

- A pet hamster that he can't bear to leave home without?

- A ridiculously oversized key ring? (Because he tends to lose his keys a lot)

- A new fashion accessory from Japan or somewhere that we've not heard about yet?

- Emergency cotton wool?

- The only part left of his Halloween bunny costme?

- A Furby? (Remember those?)

The possibilities are endless. Although none of them make any sense. So if you can shed any light on What.The.Frick is dangling from Bieber's trousers then PURLEASE fill us in.

Look, his pal Carly Rae Jepsen is even laughing at him.
