Miley CyrusMiley CyrusMiley Cyrus has taken to YouTube to react to rumours involving marriage, the police and a boob job.

And she insists that all of these rumours are false.

In a rant lasting almost 10 minutes, the 17-year-old sets the record straight about rumours that she is engaged to on-off boyfriend Liam Hemsworth.

She says: "No, I'm not getting engaged. I'm not getting married anytime soon."

Moving on to speak in the third person, she adds: "Miley doesn't need to do anything but sit and chill and enjoy life, and make good music. Music that I love, and that's the most important thing.

"I don't need any type of commitment, I'm not planning on getting married anytime soon.

"I'm not living with anybody, that's a rumour that's been going on since I got my first boyfriend ever."

"I called the cops because the paparazzi made me nervous when I was driving. They started swerving and getting up in my face while I was trying to drive.

"They put the cameras in front of my car as I was trying to reverse. I was like, 'OK, do I keep driving? What do I do? If I hit them I'm in trouble, but if I don't go I sit here and just do a free photoshoot in front of all these people that I really don't want to pay their bills…' So I called the cops."

And one other thing: "Oh, and no I don't want a boob job."

Anything else you want to clear up, Miley? For now, no. Phew.
