Miley Cyrus parodies Justin Bieber

Miley Cyrus has parodied Justin Bieber on 'Saturday Night Live'.

The singer donned a wig and appeared on 'SNL' regular skit 'The Miley Cyrus Show' where comic Vanessa Bayer plays an over-excited version of Miley.

In the sketch, fake Miley asks the real Miley (playing Justin): 'Justin Bieber, I want to ask you some things.

'Like what is your favourite album, and what is Canada like, and do you speak Canadian, and does Usher have to seat people at his own concert because he's an Usher and do you really never say never and have you gone through puberty?'

Miley (as Justin) replied: 'All I have to say that is, uh, wink,'.
