Miley Cyrushas warned Justin Bieber that he may "become a joke" if he continues with his recent bad behaviour.

TheRobin Thickecould have gone "even further".

The 20-year old admitted: "I think it's an important time not to Google myself. Honestly, that was our MTV version. We could have even gone further, but we didn't.

"No-one is talking about the man behind the ass. It was a lot of 'Miley twerks on Robin Thicke,' but never, 'Robin Thicke grinds up on Miley'. They're only talking about the one that bent over. So obviously there's a double standard."

She continued: "I wasn't trying to be sexy. If I was trying to be sexy, I could have been sexy. I can dance a lot better than I was dancing.

"Now people expect me to come out and twerk with my tongue out all the time. I'll probably never do that s**t again."
